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.
