These values may be compared with the current standard of 5 Rem in 30 years. Furthermore, recent infomation from Brookhaven's in-vivo measurements of Bikini Island residents shows average * ‘Cesium body burdens higher by an order of magnitude than those scen in 1974. A few individuals are at or above the maximum permissible body burden of 3 pCi which gives an exposure
