Yes and I find it interesting that any one would be that stupid to work near a machine that puts out radiation and would let their boss tell them oh you don't need to wear a radiation detection device.

No other work place today, in the USA, where machines are used that produce radiation is the boss allowed to tell the workers oh you can't wear radiation detection devices.

That should tell every TSA Agent standing near those machines that something is wrong when they are being exposed to radiation, but the boss doesn't want them to know exactly how much.

I mean if you are wearing a radiation detection device that turns black and Scenario 1. By the end of the day the color hasn't changed. Then the device is most likely safe, but Scenario 2. If the device turns totally black after an hour or two of being near the machine. Then you are in trouble.

I think that second one is the reason the TSA Agents who work near those machines are not allowed to wear the radiation detection devices . I think after being near the machine for a few hours that radiation detection device will turn totally black.
