Abstract
【解決手段】燃料タンク(1)はシンチレーションガラスファイバー(2)で卷装されている。燃料タンク(1)の中央部にガンマ線放出器(3)が配置されている。前記ガラスファイバー(2)に光センサ(8)が付設されている。
【選択図】図2
Description
・ガンマ放出源3の動作と質量。ガンマ放出源の動作は時間とともに指数関数的に減少する。このことは、ガンマ放出源の半減期をミッション期間に整合させることを意味している。コバルト60源の場合、半減期は約5年である。
・周囲の背景放射。それ故、この背景放射を減ずるためにブランクテストを適用する。
・ガンマ放出源3とそれぞれの検出器2との間にある材料(本ケースでは燃料4)による吸収。従って、検出した計数率は、どの程度の量の燃料4がまだタンク1内にあるかに直接依存している。
