"Tete Yarochi, Uorikku, Romurixku, Aomoen, Bikini, and Enriirikku Several 16 sq. in. tray samples at recovery read up to 200 mr/hr at 1 inch when surveyed with a AN/PDA-T1B instru- rent. (The background was 10-15 mr/hr) Most ofthe higher reedings were found in the early time intervel samples, however, detectable activity continued to be found in later samples from these stations. at Parry. Ten samples were measured for early gross decay The decay slopes ranged from -1.1 to -3.4 for the period M+3 to M+19 days. No trend in decay rate wes exhibited for either the early or late fall-out. he remainder of the , . / 7 GA .th Teeter a wae Copied /DOE LANL, J-Olw. se © PepEmERNTEOy ee orwE sew) 5. noe te Seb Gog bate yy Samples were returned to the Army Chemical Center for analysis.
