Effect of HRW on the levels of tritium in urine, serum and tissues in mice exposed to HTO. The urine excretion (A), radioactivity of urine (B), total tritium elimination through urine in the first 7 days (C), radioactivity of serum (D) and tissues (E) at day 7 in the mice treated with HTO (18.5 MBq/kg) or purified water, followed by once-daily administration of HRW or H₂O. ^@P < 0.01, compared to other groups; ^*P < 0.05, ^**P < 0.01, compared to mice treated with HTO only; ^#P < 0.01, ^##P < 0.01.
