Technical Guidance

Here you will find data and articles on radiation shielding, frequently asked questions (FAQ), monitor performance, specific gamma ray constants, mathematical derivations, radiation protection widgets  - everything we have personally found useful from our own tool kit. New resources will be uploaded here from time to time.

    Don't get too hung up on the labels  / titles applied to radiation monitoring equipment. A CPS (counts per second monitor) might be used for measurement of contamination, and might be labelled a contamination monitor, but it has other uses.

Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why each one wants what it wants.
