“…For before-and-after studies, only 6 to 10 minutes are required for isotopic decay, and therefore corrections for residual radioactivity are not required. Ionic 82Rb (specific activity, 1.5 X lo5 C i / p~) was eluted with normal saline from a portable Squibb generator (12) and infused directly into patients by means of a Harvard pump. The radiation absorbed dose for 82Rb has been estimated by Kearfott C191: per administered millicurie, the kidney (critical organ), heart, and total body receive 19, 13, and 1.6 mrad, respectively.…”
