— 25 comparisons that were made between our fallout collections on the gummed paper and the collections in a pot that sat alongside of it. DR. BRANDT: These data have been collected on the roof of this building where we have the typical stand that is used through= out the world from which we collect on two stands, a gummed sheet daily; on two other standa we collect weekly gurimed sheets and then we have two pots up there, kettles of the old GI kitchen type, #0 that we have a rather good comparison, have no standard, But of course we That 1s becsuse we do not know exactly how much is falling, . And so we are — forced then to use a regression method of reeexaluating these two types of collectors, If we took the activiiy that we get on the gummed papers, on the vertical axis and the activity that we get on the samples which can be collected in the roof part (now, these are for the weekly samples, only I'm not talking about the daily on the horizontal) we can plot the data for all the weeks and we have data now starting the 18th of January, 1954, running up to the 12th of December, 1955. . ge 0» a
