Krypton, residence time

The chemical properties of the radiation source. When a radioactive nuclide is ingested into the body, its effectiveness in causing damage depends on its residence time. For example, f Kr and gSr are both /3-particle producers. However, since krypton is chemically inert, it passes through the body quickly and does not have much time to do damage. Strontium, being chemically similar to calcium, can collect in bones, where it may cause leukemia and bone cancer. 

The solubility of ordinary atmospheric noble gases (neon, argon, krypton, and xenon) in water is temperature dependent (Benson, 1973). The stable isotope composition of precipitation (6 H, 6 0) also depends on ternperamre. If variations in these constituents can be related to a known history of temperature variation, then groundwater residence times can be estimated (Stute and Schlosser, 1993).
