PROBLEM TO BE SOLVED: To appropriately position and fix a container for measurement to an end cap of a radiation detector while suppressing absorption of radiation coming from a sample.SOLUTION: An installation fixture 10 of a container for radioactivity measurement positions and fixes a container 13 for measurement for accommodating a sample for radioactivity measurement to an end cap housing 15 of a radiation detector. The installation fixture 10 of the container for radioactivity measurement includes: a first portion 21 for positioning the outer peripheral surface of a tip of the container 13 for measurement; a second portion 22 for positioning the tip surface of the tip of the container 13 for measurement; and a third portion 24 to be positioned by the outer peripheral surface 15B of the end cap housing 15.SELECTED DRAWING: Figure 2
