we) Ar ' 66 We burned them and we checked the | meteorology at the time; we checked the reduction in weight, the reduction in volume and I can show you in the next slide quickly, what we found,¥ery briefly, these are the three successive experinenta, This is estimated activity and it's estimated from the ash and from what we found to be dictributed, This was eight tenths of milliocurie, two millicuries and seven and the per cent reduction in the ash, that ia the residual material by .way. We had thirty per cent left, that means there was a lot of glasece ware end metal parts and in each of thece cases approximately ten per cent, so we got about a ninety per cent reduction both by weight and by volume, However, on an activity basis we got a reduction of about ninety-nine per cent. In other words, only one per cent of it was found to have gotten away, In the fallout, now this fallout was measured by the same tenhnique that we used in the general fallout measurement, thet is the distribution of sticky papers elevated above the ground,
