Rontgen, the father of diagnostic radiology/X-rays There are many technical terms related to the field of radiation, such as Becquerel, Sievert, and X-ray (In Japanese, X-rays are called Roentgens). Many of these words are derived from the names of scientists who made significant contributions to radiation-related research. For example, in 1895, Wilhelm Rontgen, a German physicist, conducted an experiment

A different classification method for wastes with radioactive contamination after the Fukushima Disaster Radioactive wastes produced by nuclear facilities are classified into two categories: “high-level radioactive wastes,” which are the liquid form of radioactive residue produced in the reprocessing of radioactive fuels, and the rest of the radioactive wastes are collectively called “low-level radioactiv

Author: Masaharu Tsubokura Editors: Akihiko Ozaki M.D., Yuki Senoo 175. Issues surrounding management and disposal of high-level radioactive wastes Radioactive wastes produced by nuclear facilities are classified into two categories: high-level radioactive wastes and low-level radioactive wastes. A high-level radioactive waste is the liquid form of radioactive residue produced in the reprocessing of uranium and plutonium in spent nuclear fuel. This type of radioactive waste i
