I had studied Applied
Physics long time ago but I only focused on how to measure radiation at that
time and some radiation safety knowledge. Therefore I don’t understand why newspaper
only stated the treatment of this contaminated radioactive wastewater with Cesium
and Strontium and Tritium. Most of Cesium
and Strontium (137Cs and 90Sr) could be removed by solid-state
materials such as resins and titanosilicate zeolites but no method to handle
Tritium (3H). As I know the
fuel of nuclear plant mainly on 235U and 238U. Their radioactive family with long decay
half-life included 231Pa (T1/2=32760yr),230Th
(T1/2=75380yr), 226R (T1/2=1602yr), etc. Since the nuclear fuel was melt inside the
reactor and the cooling sea water was direct contacted. It should be included
all radioactive elements.
Finally, I believe it is the whole human problem that the whole world and all countries need to join together so as to solve it for our next generation.
