It took the dust at Xrakatoa which is 6° south three months to effect the raiiation values at Mount Peller, France and the values stayed below the normal for about years. That, of course, would mean consideravle quantities ef | dust, enough to interfere with radiation and it still migh heve been quantities for many yeare afterward which vould sot show up by such crude measurenonts. EIS§pC008 Is the data good enough so that we could plot a curve which would indicate the rate at which the dust has teen eliminated? : D277 oe (16
