How to Control Radiation?

Prime purpose of this lecture is to present on How to Control Radiation? Basic Control Methods for External Radiation: Decrease Time; Increase Distance and Increase Shielding. Minimize time of exposure to minimize total dose. Rotate employees to restrict individual dose. Maximize distance to source to maximize attenuation in air. The effect of distance can be estimated from equations. Minimize exposure by placing absorbing shield between worker and source. Last one is Monitoring.
