SAMPLE COLLECTION me ee ee ee a ee Air is drawn by pumps through paper filters at the rate of, at least, 500 m®° / day, measured by gds meter. The single daily filters are measured for gross beta radioactivity and then pooled to give monthly samples, for gamma spectrometry and radiochemical analyses, Wet and dry deposition ee ee ee ee PRTCREIRER A ie ERERS Aont AP idan 2 RR ag a b, These samples are collected monthly by means of four 1m stainless, steel funnels, having the bottom always covered with deionized water. The collected water is evaporated and the dry residue analysed. Milk is collected twice a week in four small local dairies to give 8 liters / month, About six liters dry matter are submitted to gamma spectrometry and two liters ashed for radiochemical determination of strontium-90, III - 33
