GAMMA-RAY MEASUREMENT DEVICE AND GAMMA-RAY MEASUREMENT METHOD

摘要

Provided are a gamma-ray measurement device and a gamma-ray measurement method which perform a gamma-ray measurement of simple and inexpensive structure in a mixed field of neutrons and gamma-rays. A gamma-ray measurement device is used in a method for measuring the dose in the same place when using a lead filter and when not using the filter, and obtaining a gamma dose from a difference. The gamma-ray measurement device includes a first detector which is made up of the lead filter for shielding gamma-rays and a glass dosimeter disposed in the center of the filter, and a second detector that is made up of only the glass dosimeter.

1. A gamma-ray measurement device comprising:
a first detector which is disposed around a radiation dosimeter that is the same as a radiation dosimeter constituting a second detector used together, and is formed of lead or lead alloy, wherein the first detector is made up of a filter in which the thickness is determined such that an attenuation of neutrons and a correction factor of gamma-rays are within an allowable range in the measurement of gamma rays.
