PROBLEM TO BE SOLVED: To provide a tritium concentration measurement device that continuously measures the concentration of tritium in a tritium-containing water.SOLUTION: The tritium concentration measurement device causes tritium to be adsorbed by immersing a main body having a tritium adsorbent containing manganese oxide with a spinel crystal structure containing hydrogen or lithium, into a tritium-containing water, and measures the concentration of tritium based on the physical quantity showing an index of an electron beam from the absorbed tritium.SELECTED DRAWING: Figure 1 【課題】トリチウム含有水のトリチウム濃度を連続的に計測するトリチウム濃度計測装置を提供する。【解決手段】トリチウム濃度計測装置は、スピネル結晶構造を有する水素又はリチウム含有の酸化マンガンを含むトリチウム吸着材を有する本体をトリチウム含有水に浸漬することで、トリチウムを吸着し、該吸着されたトリチウムからの電子線の指標を示す物理量に基づいてトリチウム濃度を計測する。【選択図】図１
