Measurements of the concentrations in pasture and milk samples from the surroundings of nuclear installations gave for 1989 the following average values in pasture: Be-7: 83 +- 6 Bq/kg, K-40: 900 +- 50 Bq/kg, Sr-90: 1,9 +- 0,4 Bq/kg, Cs-137: 2,9 +- 0,6 Bq/kg. Sr-89, I-131 and Cs-134 were below the limit of detection. Rest-beta-activity and rest-gamma-activity in pasture were mostly below the limit of detection. The concentration of the stabile Ca was found to be 4,4 +- 0,2 g/kg. Average concentrations in milk were: for Sr-90: 0,031 +- 0,002 Bq/L and for Cs-137: 0,16 +- 0,05 Bq/L. Be-7, Sr-89, I-131 and Cs-134 were below the limit of detection. In the national milk samples, representative for the northern, eastern, southern and western parts of the Netherlands, average concentrations were: Sr-90: 0,04 +-0,01 Bq/L and Cs-137: 0,24 +- 0,01 Bq/L. Sr-89, I-131 and Cs-134 were not detectable. From the analysis follows that the detected radionuclides which are of artificial origin are due to global fallout from nuclear tests during the sixties and Chernobyl. Concentrations in pasture as well as in milk are almost equal to pre-Chernobyl values. Only Cs-137 concentrations in pasture are still clearly higher.
