DATE: “y T, 1980 a From both ICRP=2 and ICRP 30, the uptake of cobalt from GI is sbout 30%. cesium in this respect. Thus, cobslt stiovld go with . ICHP 30 also assumes that the cobalt is uniformly distributed in the body exoept for |the liver that has five times the concentration. i 4 | I would change by adding cobalt to strontium in the third line. (... some of the atoms of strontium and cobalt will go from the stomach to the blood). Than on lines 6 and 7, T would add cobalt to cesium. (Cesium and cobalt atoms go from the blood to al) parts of the body.) Cobalt would then be eliminated in the places where it is at preadnt. 10. Parag. 121, line 7, Is it correct to say that “almost all* of the atoms of strontium, americiva and plutonium go from the blood to the bones. I cannot find a number ‘for this. for strontium in ICRP-30 but ICKP-30 uses the 40-45% split for transuranics. cf. Could we change "almost ali* to "much"7. Parag. 121, 3rd parag. (1st parag. pp. 4) line j. Again the problem with cobalt, JI would recommend ignoring it here or putting jin a sentence: “Some of the cobalt that goes from the blood to the body will remain in the body for severa) years."
