Determine the “body accumulation” and “equilibrium concentration” when Cesium-137 is ingested orally at a constant rate. The ICRP kinetic model is used for the calculations.
Specify the values in the following table for “Age Categories.”
Age Categories Description
-------- ----------------------
0.25 3 months (Assumed weight: 6 kg)
1 1 year (Assumed weight: 9.8 kg)
5 5 years (Assumed weight: 19 kg)
10 10 years (Assumed weight: 32 kg)
15 15 years old (assumed weight: 55 kg)
20 Adult (assumed weight: 70 kg)

The meanings of the “results” are as shown in the table below.
Result Description
---- ----------------------
0 The calculation completed successfully.
-1 There is an error in a variable’s value.

*“Equilibrium dose” refers to the “amount accumulated in the body” when the “oral intake” of cesium-137 equals the “amount excreted from the body.” Once the “amount accumulated in the body” reaches the “equilibrium dose,” it no longer changes.
