True.  But I was reviewing a radiation protection textbook written by
two Ph.D. medical physicists (one certified by ABR, and the other a past
president of a local HP chapter) and a radiation technologist which had
the following caption under a picture of a nuclear weapons test mushroom
cloud, "The atomic cloud top which contains man-made ionizing radiation
ascended approximately 43,000 feet above ground."  Didn't the cloud
contain man-made radioactive material which emitted ionizing radiation?
