TABLE 1 Total Dose Rates (jurad/hr) to Biota in the Northeast 

 Irish Sea from Internal Plutonium, Americium, and Polonium* 



*Basedon data from Hetherington et al. (1976) and Woodhead et al. (1976). 



TABLE 2 Summary of Estimated* Doses of "^ ^ ^Pu to C. carpio and 

 P. promelas Eggs Which Produced Effects on Hatching, Survival, 



and Abnormalitiesf 



*Except where noted, the dose is for the concentration that first produced a 

 significant effect on hatching, survival, and abnormalities. 



t Based on data from TUl et al. (1976). 



^Period of embryogenesis (C. carpio, 3 days; P. promelas. 7 days). 



S Number in parentheses is the dose at which little or no effect was observed 

 on hatching and may be considered as an estimate of the threshold dose to affect 

 hatching. 



^^^Pu per liter of water may result in a synergistic effect between chemical and 

 radiological toxicity because of the high concentration of plutonium mass present. 



These doses are within the range of e.xperimental dose rates reported in the 

 Uterature that result in damage and are clearly many orders of magnitude above 

 those experienced even in the most higlily contaminated areas (International Atomic 

 Energy Agency, 1976).
