Technical Guidance
Here you will find data and articles on radiation shielding, frequently asked questions (FAQ), monitor performance, specific gamma ray constants, mathematical derivations - indeed everything we have personally found useful from our tool kit. The resource will be gradually uploaded here from time to time. Have anything suitable that you would like to see featured here?
