PROTECTION AGAINST EXTERNAL HAZARDS

(SHIELDING)

➢ Use of shielding materials can reduce the dose rate.

➢ The process of reducing the intensity of radiation in shielding is

known as attenuation.

➢ Shielding materials and thickness depend on : Thickness

i) type of radiation Transmitte

ii) source activity d radiation

iii) energy of radiation S
