For anyone who wants the irrefutable evidence supporting these claims, this is a book you must read. I spent good money on this book and several hours reading it. Better I had done anything else. The author claims that very low levels of radiation cause almost anything bad. If it is bad, then radiation caused it.
Every bad thing is caused by radiation from bomb testing and reactors.
The author claims that these evil technologies cause a long laundry list of evils. This book is bogus science. It seems designed to continue our current plague of radiophobia. The author is ignorant of the facts and distorts information in order to convince the reader that they should be living in a lead building to protect themselves from natural radiation. A waste of money.
