The penetration of gamma-rays through water,iron, lead,and combinations of iron and lead

The dose rate attenuation of -rays is measured in iron, water, and lead for infinite geometry. The dose rate attenuation of -rays is measured in mixtures of iron and lead for barrie geometry. The experimental data obtained is compared with the results of calculations as presented in reference 1].In conclusion, the authors wxpress their deep gratitude to Doctor of Physico-Mathematical Sciences A. K. Krasin for much valuable advice and for his constant interest in the work.
