Half-Value and Tenth-Value Layers for X-ray and Gamma ray Radiation
Tables showing the Half-Value (HVL) and Tenth-Value Layer (TVL) for penetration of x-rays and gamma rays through shielding material. The data is presented for broad beam conditions with heavily filtered x-rays and for gamma radiation. Despite its age (1971 vintage) may of the values are recognisable today, appearing in modern IAEA / NCRP radiation shielding data. Use with caution (and speak to a Radiation Protection Adviser).
