Radiation: effects, risks and benefits

Emico Okuno

Severe nuclear accidents and the issue of deposition of radioactive waste are increasingly raising questions about the continuity of nuclear programs, whether for peaceful or military use. In fact, there are remaining doubts when it comes to the actual properties and applications of radiation, and the book Radiation: effects, risks and benefits clarifies them with a didactic approach.


The work allows the reader to understand the basic concepts of radiation physics, their biological effects, forms of protection and their applications in the industry and medicine, especially in the treatment of cancer. It presents the history of radiation: the discovery of radioactivity, the first radiotherapy treatments, the Manhattan project and the atomic bombs, the nuclear reactors and the main accidents involving radiation.


Radiation: effects, risks and benefits is an insightful look at the subject for students and teachers of high school and the general public who need to clearly understand and position themselves when it comes to the risks and benefits of using radiation in our daily lives.
