Iron, a badge like a Landauer dosimeter badge must be sent in to Landauer for readout. They give the dose you received over the previous month.

A pen dosimeter will work, but you need a means to charge them up. A couple of pens and a charger are around $500. Depending on what pen you get, they may saturate in a serious mishap.

Thanks for the additional info.

I believe the info I saw was referring to simple, instant readout devices like the RADSticker.

I forgot about the RADsticker. I have several in my freezer. I gave my brother a couple when he traveled to Taiwan shortly after the Fukushima accident. Yes, they're good for serious levels of radiation. They won't pick up a lantern mantle or pottery with uranium in the glaze.

At 25R for the lowest scale, this would be OK for serious events. It will tell you what you have been exposed to, but not what you are being exposed to (RadSticker won’t measure rates of exposure like a Geiger will).

I’ve got to get one! I’ll be traveling to a large cobalt source in a week or two, one that does commercial sterilization.
