FDNY "Yellow thing" attached to portable holsters

Can anyone tell me what this "yellow thing" - for lack of a better term - is, attached to the holster?

Looks to be a 4 gas meter of sorts

Looks almost like an old pass device.

Could it be for radation detector

That's the ultraradiac radiation detector and dosimeter
Carried by all ems and fire officers.
Each firefighter has one but kept in a case on the rig until needed.
