...note that X-rays are indistinguishable from low energy gamma rays. In short it's quite possible that X-rays are being produced, and being mistaken for gamma rays. The only difference is the origin of the radiation. Gamma rays come directly from the nucleus. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
