various organs are given in table A-1. The masses and densities of the organs in the adult male are given in table A-2. As an example, table A-1 indicates that 0.3% of the cardiac output is directed to the adrenals which have a radon partition coefficient of 0.7, thus the coefficient transferring radon from the large arteries to the adrenals, the terms of Eqn. A-4, has a value of

where 0.06 × 5.3 L is the volume of blood in the large arteries. The removal coefficient from the adrenals to the large veins, the term of Eqn. A-4, is

where all numerical values are from tables A-1 and A-2.

Radon is considerably more soluble in adipose tissue than other tissues of the body as reflect in the high adipose-to-blood partition coefficient listed in table A-1. The transfer of radon from the large arteries to adipose tissue, the terms of Eqn. A-4, has a value of

where is the volume of blood in the large arteries. The removal coefficient from the adipose tissue to the large veins, the term of Eqn. A-4, is

where all numerical values are from tables A-1 and A-2. The biological removal from adipose tissue corresponds to a half-time, in the absence of additional input, of about 5.4 hours.
