Protection against X rays and Gamma rays in the Industrial Field

Lesson Learned from a Case of Radioactive Contamination

“…To minimize the risk of exposure, there are three primary protection methods: (a) minimizing the duration of exposure, (b) increasing the distance from the radiation source since the exposure dose is inversely proportional to the square of the distance, and (c) employing shielding techniques. The external exposure dose can be decreased by placing a sufficiently thick shield between the person and the radiation source. , Shielding materials, such as lead, reinforced concrete, and water, can be used to reduce the external exposure dose. Lead is particularly effective and is commonly used in protective clothing and equipment.…”

Introduction

“…Because of the shapes of many of the transmission curves, HVT and TVT cannot be used to calculate primary shielding requirements: they may be used, however, to calculate the shielding required for leakage radiation. Binks (1955) c Kaye et aL (1938). a Trout and Gager (1950).…”
