2. Lucas cell - Wikipedia

   en.wikipedia.org/wiki/Lucas_cell

   A Lucas cell can be used to measure radon gas concentrations. [2] Radon itself is an inert gas.Its danger lies in the fact that it undergoes radioactive decay.The radon decay products may lodge in the lungs and bombard them with alpha and beta particles, thus increasing the risk of lung cancer.

3. Radon mitigation - Wikipedia

   en.wikipedia.org/wiki/Radon_mitigation

   A typical radon test kit Fluctuation of ambient air radon concentration over one week, measured in a laboratory. The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.

4. Radon - Wikipedia

   en.wikipedia.org/wiki/Radon

   Radon concentrations can vary daily, and accurate radon exposure estimates require long-term average radon measurements in the spaces where an individual spends a significant amount of time. [ 172 ] Radon levels fluctuate naturally, due to factors like transient weather conditions, so an initial test might not be an accurate assessment of a ...

5. Scintillation counter - Wikipedia

   en.wikipedia.org/wiki/Scintillation_counter

   They find wide application in the field of radioactive contamination monitoring of personnel and the environment. Detectors are designed to have one or two scintillation materials, depending on the application. "Single phosphor" detectors are used for either alpha or beta, and "Dual phosphor" detectors are used to detect both. [8]

6. Airborne particulate radioactivity monitoring - Wikipedia

   en.wikipedia.org/wiki/Airborne_particulate...

   The particulate radioactive material might be natural, e.g., radon decay products ("progeny", e.g., 212 Pb), or manmade, usually fission or activation products (e.g., 137 Cs), or a combination of both. There are also "gas monitors" which pass the air through a sample chamber volume which is viewed continuously by a radiation detector.

   The radon levels in some of the mines can reach 400 to 700 kBq m −3. [17] A common unit of exposure of lung tissue to alpha emitters is the working level month (WLM), this is where the human lungs have been exposed for 170 hours (a typical month worth of work for a miner) to air which has 3.7 kBq of 222 Rn (in
