Andrew Karam, Popular Mechanics - A powerful earthquake caused a massive tsunami that crashed into Fukushima Daiichi Nuclear Power Plant and caused multiple nuclear reactor meltdowns.

The Japanese government recently compensated a worker who developed leukemia after receiving just under 20 mSv (about 2 rem) of radiation exposure from the accident. See article by Jerry Cuttler and James Welsh, the acute dose radiation exposure for predicting cancer is considered to be higher than 500 mSv. The 20 mSv dose that the Japanese government compensated a person for is far below the threshold considered to cause leukemia.

Jerry Cuttler, James Welsh - A world-wide radiation health scare was created in the late 1950s to stop the testing of atomic bombs and block the development of nuclear energy. In spite of the large amount of evidence that contradicts the cancer predictions, this fear continues. It impairs the use of low radiation doses in medical diagnostic imaging and radiation therapy. No predictions of excess cancer risk should be made for an acute exposure below 50 rem, or 0.5 Sv until there is scientific evidence to support the LNT hypothesis.

Richard Zimmermann provides the reader with a book that is complete, describing with great accuracy yet in an attractive and comprehensive style all the technical, methodological and pharmaceutical aspects of nuclear medicine, covering also its diagnostic and therapeutic applications. This book proves to be a valuable information source for our young students as well as for hospital intern specialists. .. ..
