Question 1

Is this one time use only?

Accepted Answer

For immediate detection it is a one-time use because the chemical-based sensor strip does not reset. However, it is also a cumulative sensor (a dosimeter) and will continue to darken if it later detects higher levels of radiation. For instance, if today it sensed 20 mSv of radiation it would alert you within a minute. And the sensor bar (the strip between the two rows of color bars) would stay at the that level.  If later in the day it detected 50 mSv of radiation the sensor strip would darken and alert you within a minute. Again, the sensor strip would stay at that level.  If the next day it then detected higher levels, say 2000 mSv, it would darken yet again and alert you. But it does not reset back to zero. This detector was designed for first-responders, hospital staff, nuclear facilities, the military, and any one else who needed an inexpensive way to alert one to radiation.

Question 2

I have a meteoritw and several fossils id like to check for radiation. Will this suffice?

Accepted Answer

Possibly! Some radiation such as x-rays, alpha and beta particle would most likely show, but other radiation such as fast or slow neutrons would not. I don't believe gamma rays would be detected either, I'm not sure, I don't remember.

Question 3

I am flying out ,if i put this in my carry on and pass thru tsa screener, will it affect the card or expose to airport x-ray screener?

Accepted Answer

No, since the card is designed to record exposure to radiation and not x-rays.

Question 4

Is it reusable?

Accepted Answer

Depends on what you mean. If you wear it every day for 2 weeks and are exposed to radiation every few days, it will add to the previous reading and will keep track of your total exposure. You don't have to replace it each day. However, it will not reset to zero, ever.
