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.

For formal radiation safety advice, visit our Radiation Protection Adviser (RPA) services page.

    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.

Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness
