Adding filtration increases the penetration (HVL) of an x-ray beam by removing the low-energy photons. HVL values are used to judge the adequacy of the filtration. Regulations that specify filtration requirements generally state a minimum acceptable HVL value. Typical values are shown in the table below. henna thigh tattoo
