Radon concentration at the shores of large oceans is typically 1 Bq/m 3. Radon trace concentration above oceans or in Antarctica can be lower than 0.1 Bq/m 3, [100] with changes in radon levels being used to track foreign pollutants. [101] 10: 0.27 Mean continental concentration in the open air: 10 to 30 Bq/m 3.

This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...
