Almost all radioactive substances are alpha and beta emitters, and the beta emitters are frequently also gamma-sources. Any of these three forms of ionizing radiation can cause biological damage, particularly when the substance makes up a part of your body. That's precisely why radioactive substances are dangerous. What else do you think causes "long term damage"? [snip] Regards, Robin van Spaandonk <[EMAIL PROTECTED]>
