The paranoia around radioactivity is truly staggering. A few hours in a classroom is all that is needed to gain some rational sanity. Radium is an alpha emitter, which cannot penetrate the skin, as long as you do not ingest it it cannot harm you. Radon is a heavy gas so unless you are in an enclosed space it is also harmless. you are at far greater risk from eating a few Brazil nuts than from walking near or touching some glass encased Radium markers (ie none, compared to the risk from getting a paper cuts).  A half life of 1600years means it releases its energy very slowly, Tc99m which is routinely injected into people for medical imaging has a half life of 6 hrs. ie the stuff we routinely (and safely) inject into babies to look at their kidneys is 2.3 million times 'more radioactive' than Radium 226. Because radioactivity often uses vast numbers, it is easy to sensationalise, but a million times zero is still zero.<br>Treat radiation with respect and knowledge, not fear (but get your knowledge from a text book or a classroom not an internet paranoia site). No I do not think this video is being paranoid they are not the ones overreacting to this minuscule 'threat', the navy used them by the thousand as deck markers and not one sailor was ever hurt in any way by the radiation in them)
