I have purchased recently a set of radiation dosimeters used by german troops, type FH39. The set has two types of pen dosimeters, one with 50 roentgen scale and other with 500 roentgen scale. These dosimeters were basically designed to measure total ionized radiation over a long period of time, say a day or two. What I'm interested is if it is possible to convert one such dosimeter to a device which measure instantaneous radiation by attaching an amplification circuit to its ionization chamber. I'm interested to build something similar with geiger counter. I have 20 pens available so sacrificing one or two for this project would not be a problem. The problem is that I don't understand very well the physics around this subject and there may be some details that I miss. Another problem would be the calibration of such home built device. Obviously, I do not have and I will not be able to procure radiation sources so the only available source, in the best case, is to ask for help at a medical x-ray facility. I want to know if such device could be built in these conditions.
