1993:11 Methods for determination of strontium -90 in food and environmental samples by Cerenkov counting
dryness and ashed. Environmental and food samples are oven dried and ashed. The ash is dissolved in 1 molar hydrochloric acid and, at pH 1.0-1.2 the yttrium-90 is extracted from the solution with 10% HDEHP ... into 3 molar nitric acid and precipitated as hydroxide. The hydroxide precipitation is dissolved in 1 ml conc nitric acid, transferred to a liquid scintillation vial and the Cerenkov radiation from yttrium-90...

2017:18 FEM analysis of the mechanical integrity for the canister intended for storage of spent nuclear fuel with regard to copper creep ductility
vital importance. It has been shown that creep ductility for oxygen free copper can be very low (< 1 %). SKB has for this reason proposed to use oxygen free copper alloyed with small amounts of phosphorous ... criteria and postulated material behavior. Results show a required creep ductility in the range of 1% to 10%. It is concluded that the method used for this analysis is quite sensitive to several parameters...

2003:13 Personalstrålskydd inom kärnkraftindustrin under 2002
bröts år 2002 (se figur 1). Den främsta orsaken till detta var genomförandet av stora moderniseringsprojekt vid reaktorerna Oskarshamn 1 och Barsebäck 2. Arbetena vid Oskarshamn 1 pågick under hela 2002 ... övriga reaktorer blev dock stråldoserna i samband med 2002 års revisionsarbeten låga. Vid Ringhals 1 blev stråldosen den lägsta sedan startåret, 0,7 manSv. Låga revisionsdoser erhölls även vid reaktorerna...
