Environmental status of the Hanford reservation for January--June 1969
Environmental status of the Hanford reservation for January--June 1969
Data are presented on the radioactivity in environmental samples collected within the Hanford plant boundaries during the first six months of 1969. Data are included on the total BETA activity and content of /sup 90/Sr and tritium in samples of Columbia River water; the total BETA activity in samples of drinking water; the total alpha and BETA activity and content of /sup 137/ Cs, /sup 51/Cr, and /sup 65/Zn in samples of su rface waters; the content of /sup 32/P, /sup 40/K, /sup 134/Cs, /sup 137/Cs, and /sup 65/Zn in the tissues of game birds feeding on the area; the total BETA activity and content of /sup 131/I in samples of surface air; the total alpha , total BETA , and total gamma activity and content of /sup 95/Zr-Nb, /sup 106/Ru, /sup 131/I, /sup 137/Cs, /su p 140/Ba, and /sup 144/Ce in samples of air filters; the total alpha and total BETA activity and content of /sup 137/Cs and /sup 144/Ce in samples of vegetation; and results of aerial surveys of gamma activity conducted at an altitude of 500 feet. Estimates were made of the average external gamma exposure rates of personnel. Increased BETA activity in the atmosphere was duemore » to fallout. (CH)« less
