Technical Radiation Protection

During our Radiation Protection Supervisor (RPS) training courses we reassure delegates that there is very little in the way of complicated maths or physics – its generally not important when working safely with ionising radiation (understanding the concepts are important). However, there is a good dose of physics and mathematics behind these concepts and principles which is what you will find in this area of the site. Mathematical derivation, shielding calculations, and other health physics concepts are featured.

    Consider the situation where you move up to a radioactive source, perform some operations for a period of time, and then move away. What total dose will be received?

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