The aim of this webinar was to provide an awareness of methods available to determine shielding requirements for simple exposure conditions.

The presentation covered simple shielding geometry using the point source approximation, gamma ray constants, linear attenuation coefficient, transmission and build up factors, as well as half and tenth value layers (HVL/TVL). The presentation referred to BS 4094: Part 1 : 1966, DATA ON SHIELDING FROM IONIZING RADIATION, Part 1. Example calculations were presented.
