69 examined the deta end it immediately occurred to us that maybe something was interfering with our analysia. There was a drizzle and rain throughout the dey, and we went back to our fallout information to find out waa eomebody else experiencing a similar phenomenon, And, sure enough we found that this wae done at Buffalo and the cities of Detroit and Cleveland each had fallouts of the order of 500 disintegrations per minute per square foot. And so we feel a little bit secure in saying that the fallout line was like this and then 414 in fact, level off because we were hitting a ®rombé degree background, Deducting this figure, 2 think we deducted 400 disintegrations per minute per .- equare foot from the data which again gives us a fellout curve which is not nearly as good a fit to the "Sutton® equation as the other one is, but putting the proper pira- meters in, it does fit pretty well. And, so we believe that we have this thing pretty well in hand, That the amount of contemination from such a burne ing is very minimal, It could not poseibly Lt
