Abstract
Summary
Young chicks were exposed to 1000 r X radiation at dose rates of 6 or 43 r per minute. Determinations of excretion rate of urate and phenol red and of blood urate levels indicated that death in the initial period (within 8 to 24 hours) following high rate exposures was preceded by renal failure and a rapidly developing azotemia. Individuals that survived 24 liours or more after exposure, whatever the dose nate, continued to excrete at a normal rate. Phenol red retention invariably accompanied failure of urate excretory function.
