How to Calculate Half Value Layer
What is Half Value Layer?
A half-value layer (HVL) calculator determines the thickness of material needed to reduce radiation intensity by 50%. HVL depends on the radiation energy and shielding material. Lead HVL for 100 keV X-rays is about 0.12 mm; concrete HVL is ~1.7 cm. Medical and nuclear shielding design depends on HVL calculations.
