Evaluation of attenuation properties of lead glass used for radiation shielding applications

Radiation Protection and Environment
Lead glass, a material containing lead oxide, is widely used for radiation shielding due to its ability to attenuate radiation while remaining optically transparent.

Radiographic assessment of protective aprons and dose simulation to personnel

Journal of Radiation and Cancer Research, 2019
Background: Studies have shown that protective aprons are carelessly handled after working hours. This, in turn, leads to crack, tear, hole, and creases on the apron, which may lead to distortion in the attenuating property and hence reduction in ...

Conversion coefficients from fluence and air kerma to dose equivalent quantities

Journal of Radiological Protection, 1990
Following the publication of the International Commission on Radiation Units and Measurements Report 39 (ICRU, 1985), the British Committee on Radiation Units and Measurements issued a memorandum (BCRU, 1986) recommending the adoption of the quantities ambient dose equivalent H*(d) and directional dose equivalent H'(d) for area monitoring in the UK ...
