A set of calculation tools (total of 13) covering most of the field in radiation protection: gamma, beta and neutron external exposure, internal exposure, atmospheric transfer and more. You will find on this site explanatory videos for each tool and their validation files (downloadable pdf).
We offer you other videos dedicated to nuclear physics, radioactivity, radiation-matter interaction, statistics and metrology...
I use DOSIMEX, which gives me total satisfaction, both by the quality of its results and its ease of use, in the training of personnel from the Ministry of the Armed Forces. It has, among other things, the strength of taking into account common situations faced by MinArm agents, both in the roles of medical PCRs (thanks to the X-ray calculation module!) as well as those involved at all levels in the industrial field (from PNR to engineer). Finally, it is so easy to use that almost all the PCRs we train have adopted it in their units.
