Measure the radioactivity of the test object in its original shape, easily, quickly, and with high precision.
In gamma-ray measurements using a radiation measurement device, self-absorption of gamma rays within the measured object, such as food, cannot be ignored, necessitating correction for self-absorption. Therefore, the measured object is finely crushed and packed tightly into a Marinelli container for radiation measurement. However, the process of chopping and packing the measured object is cumbersome and labor-intensive. Additionally, because the food is crushed into a fine state, there is a challenge in distributing the food used for measurement.
The present invention enables the provision of a non-destructive radiation measurement device and method that allows for the easy measurement of the specific radioactivity of the measured object, such as food, without finely destroying it. The non-destructive radiation measurement device of this invention includes a gamma-ray detection unit, a counting unit, a mass measurement unit, and a calculation unit for calculating the specific radioactivity of the measured object. This allows for easy, quick, and highly accurate radiation measurement of the measured object, such as food, without the need to chop it up.
