Personal dose equivalent conversion coefficients for electrons to 1 GE V

Abstract

In a previous paper, conversion coefficients for the personal dose equivalent, H p(d), for photons were reported. This note reports values for electrons calculated using similar techniques. The personal dose equivalent is the quantity used to approximate the protection quantity effective dose when performing personal dosemeter calibrations and in practice the personal dose equivalent is determined using a 30330315 cm slab-type phantom. Conversion coefficients to 1 GeV have been calculated for H p(10), H p(3) and H p(0.07) in the recommended slab phantom. Although the conversion coefficients were determined for discrete incident energies, analytical fits of the conversion coefficients over the energy range are provided using a similar formulation as in the photon results previously reported. The conversion coefficients for the personal dose equivalent are compared with the appropriate protection quantity, calculated according to the recommendations of the latest International Commission on Radiological Protection guidance. Effects of eyewear on H p(3) are also discussed.
