Measuring method of strength of radioactivity of tritium of drum of radioactive waste

摘要

(57) Abstract Topic Not to be harmful, reliability is high, being the technology which is economic, unknown free volume it is to offer the technology which makes that the radioactivity of the tritium conversion waste which is accommodated in the bag which is located inside the drum which possesses an unknown leak is quantized possible. Solutions The drum of the radioactive waste which includes with the radioactive waste (2) and free volume (1) being measuring method of strength of the tritium radioactivity, it features that the fact that strength of the radioactivity of the tritium which is included in the radioactive waste (2) from thing and this value which measure the quantity of ³ He which are formed by the collapse of the tritium which is included in the aforementioned radioactive waste (2) between stipulated times corresponds is presumed is had.
