Abstract:
The International Organization for Standardization (ISO) has issued a standard series on photon reference radiation qualities (ISO 4037). In this work, conversion coefficients from air kerma to dose equivalent quantities not included in ISO 4037-3 are supplied for the following quantities: For H(p)(0.07) for X and gamma radiation qualities for the rod, the pillar and the slab phantom and for H(p)(3) for X and gamma radiation qualities for the slab phantom. In addition, an overview of conversion coefficients suggested for use for all quantities relevant in radiation protection is provided.
