A Simple α-Particle Irradiation Chamber for the Calibration of Dosimeters

Abstract

An apparatus applied to α-particle irradiation experiments in dosimetric materials was designed and the performances were tested.
The characteristics of the apparatus were as follows. (1) The particle flux density of 10² cm^-2⋅s^-1 and the energy flux density of 10^-3 erg⋅cm^-2⋅s^-1 were available. (2) The irradiation conditions such as the energy and flux density of α-particles or the irradiation time could be regulated independently of each other. (3) The apparatus could be simply constructed and simply operated, for example, it could be used also in the area other than the radiation controlled area.
