Abstract
This work introduces a mathematical formula to calculate the attenuation coefficient of a cylindrical sample placed on the top of a well-shaped gamma-ray detector. The formula depends on calculations of the average path length of the photon through a sample and the effective solid angle. The obtained results using the introduced formula are compared with the NIST XCOM database and also compared with the experimental work using two different-sized detectors and sources located in two different positions. A remarkable agreement between both was observed, which proves the validity of this formula.

期刊介绍：
Radioprotection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes (theoretical and practical aspects): dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments.
