RM-2 radon detector

rm2 radon detector

Facility:

RM-2 radon detector

Staff:

Dr. Quentin Crowley

Location

Museum Building, TCD

Instrument:

  • portable instrument for in-situ measurement of soil gas radon concentration
  • the RM-2 Radon detector is designed for in situ rapid and accurate analysis of radon (222Rn) in soil gas
  • it is well applicable to radon risk mapping and assessment of radon content in foundation soils
  • its unique characteristics it can be used as well for various geophysical applications such as uranium exploration, assessment of radon at uranium mines and uranium tailings, geochemical mapping

Notes:

Uranium and thorium generate by their decay radioactive gases radon (222Rn, T½ = 3.82 days) and thoron (220Rn, T½ = 54.5 seconds), both sources of alpha radiation, which differ by their half-lives T½.

Additional information:

Radon detector RM-2 consists of a set of fifteen ionization chambers IK-250, the reader ERM-3 and a soil-gas sampling set. Samples of soil-gas are collected through hollow steel rods by means of a plastic large-volume syringe and transferred to evacuated ionization chambers.
