What is it about?

After Fukusima-Daichi accident public opinion is against the establishment of new nuclear reactors. The old reactors are also facing threat for shut down. This issue has raised scarcity of beneficial radioisotopes, especially used for diagnosis and therapy of mankind. What can be the alternative? We proposed that when lead-bismuth eutectic (LBE) is bombarded with very high energy proton beams (of the order of giga electron volt), then due to extreme us-restful state of the nucleus, large numbers of useful radioisotopes will be produced inside the target. But again the challenge is how to get them in pure state individually? As a first step lexical separation has been proposed, i.e., bulk lead and bismuth would be separated first, then the large numbers of radionuclides will be distributed in two phases. Then the separation will be easier.

Why is it important?

This is important in view of the separation of large number of radioisotopes, which have beneficial role for humankind, that would be produced in lead bismuth eutectic if bombarded by high energy protons.


I hope that this article will be helpful to the people who will in future produce, separate and supply the pure radionuclides produced in lead bismuth eutectic,
