UNCLASSIFTED APPENDIZ A ANALTTICALPRCCEDIRES. The analytical methods used for determining total radiostronthim, total strontium, Sr*° and radium are given in detail in this apnendix. The majority of the samples encountered were bone,| soil, vegetation and foeds. Where different orocedures are require for handling these different types of samoles, the methods are gifen separately. The actual methods are orefaced by charts for determining the theoretical contribution of radiostrontium to total fission pmpduct activity and the S5r7°/5r®* activity ratio as a function of ti gince burst. - The methods reported are those actually used in the analyses shown in this report, but a summary of analytical develcpments in prgeress is given at the end of this appendix.
