Title (EN) DOSIMETER CONTAINER AND DOSE MEASURING BODY
(FR) RÉCIPIENT DE DOSIMÈTRE ET CORPS DE MESURE DE DOSE
(JA) 線量計容器及び線量計測体
Abstract:
(EN) 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).
(FR) L’objectif de la présente invention est de réaliser un récipient de dosimètre qui contribue aussi bien à un accroissement de la précision de mesure de la dose de rayonnements et à une réduction de la taille d’un dispositif de mesure. Le récipient (10) de dosimètre selon la présente invention comporte une partie de logement (11) et une partie de blindage (12) entourant la partie de logement (11). La partie de logement (11) loge un instrument de mesure de dose de rayonnements qui mesure une dose d’un rayonnement prescrit autre que les faisceaux de neutrons. La partie de blindage (12) comprend un organe en un matériau qui est transparent au rayonnement prédéfini susmentionné et qui est opaque aux faisceaux de neutrons. La partie de blindage (12) est de préférence un corps fritté de LiF, en particulier un corps fritté de 6LiF. La partie de blindage (12) a au moins deux organes constitutifs (une partie de corps principal (12A) et une partie de couvercle (12B)) de partie de blindage, et des organes adjacents peuvent buter l’un contre l’autre, et mieux encore peuvent s’accoupler l’un à l’autre. La taille de la partie de logement (11) est sensiblement égale ou supérieure à la taille de l’instrument de mesure de dose de rayonnements, et la partie de logement (11) s’étend à travers tous les organes constitutifs. Le récipient (10) de dosimètre convient à un usage en tant que corps de mesure de dose (1) dans lequel un instrument de mesure (51) de dose de rayonnement est logé dans la partie de logement (11).
(JA) 放射線量の測定精度の高度化と、測定装置の小型化との両方に寄与する線量計容器を提供する。 本発明の線量計容器(10)は、収納部(11)と、収納部(11)を囲む遮蔽部(12)とを備える。収納部(11)は、中性子線以外の所定の放射線の線量を計測する放射線量計測器を収納する。遮蔽部(12)は、上記所定の放射線を透過し、中性子線を遮蔽する材料の部材からなる。遮蔽部(12)は、LiF焼結体、特に、LiF焼結体であることが好ましい。遮蔽部(12)は、少なくとも2つ以上の遮蔽部構成部材(本体部(12A)及び蓋部(12B))を有し、隣り合う部材は、互いに突き合わせ可能、より好適には、互いに嵌合可能である。収納部(11)の大きさは、放射線量計測器の大きさと略同じかそれよりも大きく、収納部(11)は、上記構成部材の全体にわたって延在する。線量計容器(10)は、収納部(11)に放射線量計測器(51)が収納された線量計測体(1)として好適に用いられる。
