Title:
DOSIMETER CONTAINER AND DOSE MEASURING BODY
Document Type and Number:
WIPO Patent Application WO/2018/181395
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a dosimeter container which contributes both to an increase in radiation dose measurement accuracy and a reduction in the size of a measuring device. The dosimeter container (10) of the present invention is provided with an accommodating portion (11) and a shielding portion (12) surrounding the accommodating portion (11). The accommodating portion (11) accommodates a radiation dose measuring instrument which measures a dose of prescribed radiation other than neutron beams. The shielding portion (12) comprises a member of a material which transmits the abovementioned prescribed radiation and shields neutron beams. The shielding portion (12) is preferably a sintered body of LiF, in particular a sintered body of 6LiF. The shielding portion (12) has at least two shielding portion constituent members (a main body portion (12A) and a lid portion (12B)), and adjacent members are capable of abutting one another, and more preferably capable of mating with one another. The size of the accommodating portion (11) is substantially the same as or larger than the size of the radiation dose measuring instrument, and the accommodating portion (11) extends through all the constituent members. The dosimeter container (10) is suitable for use as a dose measuring body (1) in which a radiation dose measuring instrument (51) is accommodated in the accommodating portion (11).
