2. 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.

3. Radiation monitoring - Wikipedia

   en.wikipedia.org/wiki/Radiation_monitoring

   Source monitoring is a specific term used in ionising radiation monitoring, and according to the IAEA, is the measurement of activity in radioactive material being released to the environment or of external dose rates due to sources within a facility or activity.

4. Dosimetry - Wikipedia

   An example of this is radon monitoring. The largest single source of radiation exposure to the general public is naturally occurring radon gas, which comprises approximately 55% of the annual background dose. It is estimated that radon is responsible for 10% of lung cancers in the United States.

   Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.

6. Counts per minute - Wikipedia

   en.wikipedia.org/wiki/Counts_per_minute

   The continuous current ion chamber instrument can easily measure dose but cannot measure counts. However the Geiger counter can measure counts but not the energy of the radiation, so a technique known as energy compensation of the detector tube is used to produce a dose reading. This modifies the tube characteristic so each count resulting from ...

7. Health effects of radon - Wikipedia

   A Lucas cell is also an active device, or one that requires power to function. Active devices provide continuous monitoring, and some can report on the variation of radon and interference within the testing period. These tests usually require operation by trained testers and are often more expensive than passive testing. [105]
