Jul 13, 2021 at 16:40 comment added LSerni @user it turns out someone else had very much the same idea :-D - there is also a thermoluminescent bracelet. landauer.com/saturn-ring-dosimeter
Jul 13, 2021 at 16:37 comment added LSerni @user not that I know of, but you could make one using a doped lithium fluoride crystal in a ring cast. The crystal would absorb the radiation, which could be quantified by placing the ring into a special heater (it's called thermoluminescent dosimetry). It would also be possible to use one of those liquid crystal rings that change color with the body temperature, filling them with extreme UV photographic gel and coating them with UV-filtering paint. Only radiations would then enter the crystal, which would slowly change color in response to radiation. Not very precise, but it would work.
Jul 13, 2021 at 16:28 comment added user Are there any jewel-like dosimeters? Such that can be checked for visual indications of radiation without special process?
Jul 13, 2021 at 11:51 comment added LSerni @Cadence you can find reliable palm-sized ones on Amazon. It's more difficult for neutrons, which aren't EM spectrum and have a wide range of energies, but X and gamma can be tracked on the cheap.
Jul 13, 2021 at 11:48 comment added Cadence When you say active detectors are bulkier, are we talking something you'd put in the back of a truck, or more the size that, say, a bodyguard could carry in an attache case?
