Spinthariscopes are very nice! You can still buy them! http://unitednuclear.com/index.php?main_page=index&cPath=2_12
About the danger: There is literally no danger about the scope, because the particles you see are mostly alpha-radiation that do not pass through the looking glass. Alphas rarely can pass paper... Also Radium in clocks would only cause potential danger if you would keep your clock all the time in your pocket - or whats way worse - the radium would get out of the clock and into your body. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
