Popular scanner myths

[br0adband]

And as for the possible interference in hospitals, I've seen it myself:

Tons of them, especially in the cardiac and intensive care wards, now use a ton of wireless hardware rigged to transceivers and small packs the patients where so they can be mobile. Instead of having to drag stuff around, they put the pack on the patient and they aren't restricted to their beds much anymore. I had some chest pains a few years back (they never did figure out what caused 'em) and I wore such a device overnight while I was there. When I received a call, it triggered the monitor I was wearing and then I ended up having 3 nurses in my room in under 15 seconds all over me while I was trying to make them realize nothing was wrong. A quick check of my pulse confirmed it, and when the friend called back before they left the room, we all realized what caused it: my phone. Obviously, it was turned off with much haste.

Just walking through any hospital nowadays you can spot Wi-Fi antennas and access points all over the place. Might be an issue, might not, but cellphones aren't the only devices people use. Imagine someone trying to use a laptop in an area where the cardiac monitors are all working in the same frequency band/range. Talk about a nightmare just waiting to happen...

"A scanner or any electronic device can cause interference to hospital equipment or on a airplane."

Sure, just bring one with you and see how much interference the staff causes you.

"A cell phone or high voltage power lines are bad for your heath."

They cause genetic mutations, people walk around with cell phones growing out of their ears and linemen grow rubber hands.

"And the last one power lines can cause interference to the scanner or TV."

Only when a defect causes leakage which is usually the case but if the voltage is high enough it leaks all by itself, just stand under a high tension pylon and listen to the snakes hissing up there. Then try to hear anything in AM mode and you can watch all the pretty sparkles on TV.

As for stupidity have you noticed Americans get dumber every day? It's power lines and electromagnetic devices turning brains to mush. The future belongs to computers and robots, it's all in the plan, your grandchildren will serve the machines you have created.

So you where in the room and some one came in with a cell phone and the cell phone cause the alarm?

What would happen if the doctor had a cell phone and a some one called the doctor would the alarm go off?

Whats the frequency of Wi-Fi .

"A scanner or any electronic device can cause interference to hospital equipment or on a airplane."

Thats why they say turn it off when taking off or landing!!! Other thing just driving by some hospitals not even on the grounds and try to pick up some thing liike 800 Mhz its lke trying to pick up some thing with the broken scanner!!

I did not know at the time if it was interference or I needed a stronger and better antenna to bring in the weak radio signal..

Its pointless driving any where in my city with a scanner do to the picket fencing.The only place you can hear it if you stop the car and away from most tower sites.

So you where in the room and some one came in with a cell phone and the cell phone cause the alarm?.

It could. There are a lot of variables at work.

A scanner or any electronic device can cause interference to hospital equipment or on a airplane.

I've been in the hospital three times in the past year. Had my scanner, cell phone, and laptop (wi-fi) each time. Never seemed to create a problem. Though i didn't have any extra hardware other than an IV pump connected to me. There's a lot of stuff that seems to be going around the hospitals. People with cellphones, most doctors and nurses have pagers, Wi-Fi, security with their radios. Unless something like a cell phone is operating right next to a medical device i think its pretty safe.

I was on one of those "cardio iPods" for a few days last spring and there was no problem with my cellphone.

Apparently there is much variation between the systems.

Fun interference

Back in the mid 80s I discovered a neat trick. I had a Uniden PC122 cb tweaked to 12w (Hey that's illegal!!) mounted in my car. By pure coincidence, I was behind a car that had one of the dinosaur model cell-phones in it and could see the driver talking. I keyed up to talk to a friend of mine on the radio and noticed the driver holding the handset of his phone away from his ear and looking at it. I told my friend to stand by and started following phone guy. When he started talking on his phone again, I keyed up and sure enough it appeared as if I was interfering with his phone. Once I discovered this I quickly became the mystery pain in the a$$ to anyone I found talking on a cell phone in a car.

My best guess is that the only reason I caused problems for them was the very close proximity to their phone. 15 feet or so between the two antennas and it seemed to be enough to provide me with entertainment in heavy traffic.

Yes, I was a horrible person back then.

Since your CB radio was essentially mis-tuned to get 12 watts of output, I am sure you were not just transmitting on 27 MHz. When properly tuned your CB would not put out (as much) spurious radiation.

Next time you're in the hospital let us all know and we'll bring down lots of our equipment to pass the time. But personally I'd rather not take the chance. Thankyouverymuch.

Nooo, as an expert, (I work in Biomed at our local hospital), scanners do not interfere with Medical Equipment. 2-way's on the other hand do, quite a bit. We have, as most hospitals do policies in place for that.

 

[nec208]

So how much EMF does it need or what determines the condition?

Why some devices more than others.

May be thats why you go driving with a scanner and some tower sites you get interference.Some hospitals just on the grounds you get nothing and others no problem.

It was a big problem at one of the hospitals here the PD and FD radios got lots of interfere and could not talk on the radio and the FD had to use talkaround here.There is lots and I mean lots of electronic at hospitals they use and may be one had lots of EMF and causing interference to the PD or FD radio.

Ever notice how many hospitals are tall buildings. Take a look at these hospital roofs.
Most have a lot of paging and/or other base station transmitter antennas. Many of these
run at very high power levels(100 watts or above).

Exactly. Those 500 watt VHF paging transmitters splattering all over the band will never cause any interference, but your ¼-watt cellphone will. I know of hospitals that have cell sites on top of them. 'Nuff said!

Some research has found that exposure to elevated levels of ELF magnetic fields such as those originating from electric power transmission lines may be implicated in a number of adverse health effects. These include, but are not limited to, childhood leukemia [10], adult leukemia[11], breast cancer[12], neurodegenerative diseases (such as amyotrophic lateral sclerosis)[13][14][15], Miscarriage[16][17][18], and clinical depression. Although there seems to be a small statistical correlation between various diseases and living near power lines, the physical mechanism is not clear. One proposed mechanism is that the electric fields around power lines attract aerosol pollutants.[19][20]

One possible response to the potential dangers of overhead power lines is to place them underground. According to the British Stakeholder Advisory Group on ELF EMFs[21], the cost of burying cables at transmission voltages costs is around GBP 10M/km, compared to GBP 0.5-1M/km for overhead lines.

Underground cables eliminate the electric field and reduce the width over which the magnetic field is elevated.[22] However, in reality, protection from the dangers of electromagnetic (EM) fields is seldom the driving concern when burying power lines.

The strongest evidence linking EMF to cancer was fabricated. Most people, when quizzed, have heard of the link between EMF's and cancer, but relatively few people have heard of the fabricated data leaving a public perception that power lines are far more dangerous than they are.[6] Indeed, the UN World Health Organization has concluded "...a cause-and-effect link between ELF field exposure and cancer has not been confirmed

EMF Frequently Asked Questions

Consider for a moment the fact that some companies have an interest in swaying information one way or another. For example, the cell phone companies will all tell you there are no risks associated with extended cell use. So now take a moment to read what is posted about EMF at the PG&E web site:
http://www.pge.com/myhome/edusafety/systemworks/electric/emf/faqs/index.shtml

 

[nec208]

Electric and magnetic fields (EMFs) are invisible lines of force associated with the production, transmission, and use of electric power such as those associated with high-voltage transmission lines, secondary power lines, and home wiring and lighting. Electric and magnetic fields also arise from the motors and heating coils found in electronic equipment and appliances.

Because the use of electric power is so widespread, humans are constantly exposed to electric and magnetic fields. Studies conducted in the 1980s showed a link between magnetic field strength and the risk of childhood leukemia. After reviewing more than two decades of research in this area, NIEHS scientists have concluded that the overall pattern of results suggests a weak association between increasing exposure to EMFs and an increased risk of childhood leukemia. The few studies that have been conducted on adult exposures show no evidence of a link between residential EMF exposure and adult cancers, including leukemia, brain cancer, and breast cancer. Based on these reviews, the NIEHS recommends continued education on practical ways of reducing exposures to EMFs.

EMF power line controversies
http://www.quackwatch.com/01QuackeryRelatedTopics/emf.html

Electric and magnetic fields (EMF) are invisible lines of force that surround any electrical device that is plugged in and turned on. EMF are made up of waves of electric and magnetic energy moving together (radiating) through space. Electric fields are produced by electric charges and magnetic fields are produced by the flow of current through wires or electrical devices.

EMF is commonly associated with power lines. A person standing directly under a high-voltage transmission line may feel a mild shock when touching something that conducts electricity. These sensations are caused by the strong electric fields from the high-voltage electricity in the lines. They occur only at close range because the electric fields rapidly become weaker as the distance from the line increases.

Many people are concerned about potential adverse health effects. Much of the research about power lines and potential health effects is inconclusive. Despite more than two decades of research to determine whether elevated EMF exposure, principally to magnetic fields, is related to an increased risk of childhood leukemia, there is still no definitive answer. The general scientific consensus is that, thus far, the evidence available is weak and is not sufficient to establish a definitive cause-effect relationship.

In 1998, an expert working group, organized by the National Institute of Health’s National Institute of Environmental Health Sciences (NIEHS), assessed the health effects of exposure to extremely low frequency EMF, the type found in homes near power lines. Based on studies about the incidence of childhood leukemia involving a large number of households, NIEHS found that power line magnetic fields are a possible cause of cancer. The working group also concluded that the results of EMF animal, cellular, and mechanistic (process) studies do not confirm or refute the finding of the human studies. The International Agency for Research on Cancer (WHO) reached a similar conclusion

Some doctors say if you smoke pot you will get cancer and others say not..Others say when you smoke pot you kill brain cells and others not.

http://www.enews20.com/news_Medical_Marijuana_Endorsed_by_US_Doctors_Group_05880.html

The second-largest group of doctors in the United States has approved Friday the use of marijuana for medical purposes, issuing a policy statement on medical marijuana this week.

The American College of Physicians, with 124,000 members, asked the U.S. government to cancel the ban on using marijuana for treating some patients or for medical experiments, stating that the research found that the non-smoked forms of THC (tetrahydrocannabinol), (the main psychoactive element in marijuana), have been efficient in treating weight loss caused by AIDS, and nausea and vomiting pursuant to chemotherapy in cancer patients.

The doctors group urges the federal government to legalize marijuana and exclude it from the so called Schedule I, a drug category also containing illegal drugs such as heroin and LSD. Moreover, the ACP calls for protection of both doctors and patients from criminal and civil penalties in the states where medical marijuana laws have been adopted, the Los Angeles Times informs. A dozen states have already adopted laws which allow the use of marijuana as medicine.

The ACP also advises the government to ease the approval process of research on marijuana, which could lead to more accurate data related to the therapeutic value of the plant.

“Additional research is needed to clarify marijuana's therapeutic properties and determine standard and optimal doses and routes of delivery. Unfortunately, research expansion has been hindered by a complicated federal approval process, limited availability of research-grade marijuana and the debate over legalization,” the Philadelphia-based doctors group aid.

The White House Office of National Drug Control Policy seemed to be unimpressed by the findings. David Murray, chief scientist said: “This is not medical science. This is a policy paper. A political act calling for political response.”

Murray stated that medical organizations, such as the American Medical Association, the National Cancer Institute, the American Cancer Society, and the National Multiple Sclerosis Society are against using marijuana as medicine. The White House’s Office of National Drug Control Policy said the FDA should decide whether or not to issue approval of marijuana as medicine

It looks more like the pharmaceutical companies don't want this coming out.Not do say the propaganda lies the Ronald Reagan came up with.And the horrible drugs the pharmaceutical companies give you ..

Is there any study that claim it impairs your memory.


The conspiracy of drugs,global warming,EMF,foods,Not enough sleep or stress out at work,NOT enough sunlifgt leads too xx seem more that groups want to just make the front page of the news.

A cell phone or high voltage power lines are bad for your heath.

Just read another article about that today. They were complaining about the fact that all the cell phone sponsored investigations prove it isn't, and all the other ones prove it is. It's non-ionizing radiation, so I wouldn't expect it to be cancer causing. Any RF that's strong enough will cause some amount of body heating that can be bad for you (eyes are especially sensitive and bubbles can form), but that requires more output than you're going to get out of a cell phone. Dunno. Time will tell...

This is a multipurpose unit designed to neutralize EMF’s and or Geopathic Stress. For EMF protection it produces a 7.83 Hz field (Schumann Resonance) which blankets a 20,000 sp ft area. This has the effect of overcoming the negative EMF fields. For Geopathic Stress the unit detects and then amplifies the waves REVERSING in phase by 180 degrees and retransmitting them which has the effect of neutralizing them (similar to noise cancellation technology).

Someone does not understand their physics very well. In order for 2 waves to cancel each other out, they should be the same frequency but opposite phases. Otherwise there are points where the two signals ADD to each other.

I was more worried about the rumors that if a guy smoked too much pot his breasts would grow.
