Claims

[Scope of utility model registration request]

(1) A constriction part that is provided in a process pipe through which process fluid flows and narrows the flow path in the pipe, and a pressure loss of the process fluid that is provided to connect the upstream and downstream sides of this constriction part and that circulates inside. A bypass pipe whose resistance is set to be smaller than the pressure drop resistance generated by the constriction part, a radiation detection part provided in this bypass pipe, a flow rate detector that detects the flow rate of the process fluid, and this flow rate. 1. A process radioactivity measurement device comprising: a measurement section that calculates a process radioactivity concentration by inputting a flow rate detection signal from a detector and a radiation detection signal from the radiation detection section.

(2) The process radioactivity measuring device according to claim (1), wherein the constriction portion is an orifice.

(3) The radiation detection section includes a process fluid distribution container that is detachably connected to the bypass piping and has a detector storage recess, and a process fluid that is housed in the detector storage recess and that flows through the process fluid distribution container. 1. A process radioactivity measuring device according to claim (1) of the utility model registration, characterized in that the device comprises a radiation detector for detecting a radiation dose of .
