Abstract
A method for removing a radioactive noble gas from a gas volume, includes: (a) providing the gas volume such that a dew point of the gas volume at a gas temperature of 20° C. is −20° C. or less, preferably −30° C. or less, more preferably −45° C. or less; and (b) passing the gas volume over a bed of a microporous molecular sieve including a transition metal disposed on and/or in the microporous molecular sieve, thereby adsorbing the radioactive noble gas to the bed.

A method for removing a radioactive noble gas from a gas volume, comprising:
- a) providing the gas volume such that a dew point of the gas volume at a gas temperature of 20° C. is −20° C. or less;
- and
- b) passing the gas volume over a bed of a microporous molecular sieve comprising a transition metal disposed on and/or in the microporous molecular sieve, thereby adsorbing the radioactive noble gas to the bed;
- wherein the radioactive noble gas is Rn, and
- wherein the microporous molecular sieve is an ETS-10 or ZSM-5.
An apparatus for removing a radioactive noble gas from a gas volume, comprising:
- i) one or more moisture adsorbent beds, and
- ii) one or more noble gas adsorbent beds of a microporous molecular sieve comprising a transition metal disposed on and/or in the microporous molecular sieve, the noble gas adsorbent beds having an input coupled to an output of the moisture adsorbent beds;
- wherein the radioactive noble gas is Rn, and
- wherein the microporous molecular sieve is an ETS-10 or ZSM-5.
