Three, five to thirteen-day long radon progeny monitoring periods were conducted inside a sealed room of a residential house and outdoors at an open cut uranium mine. The average unattached fraction of radon progeny was measured to be between 0.09 and 0.14 for the residential house, and between...
In 2007 Canada dropped it’s “Action Level” from 800 bq/m3 to 200 bq/m3 in response to multiple 2005 research reports linking residential radon levels to lung cancer. European countries such as Britain and Germany have gone further and dropped their “Action Level” to 100 bq/m3. The Wo...

The AlphaGUARD PQ2000 PRO monitor has an alpha spectrometer using an ionization chamber. The device was used in the diffusion mode over 60-min cycles for 24 h and the resulting time-averaged value was assumed to be the radon concentration. The RAD7 detector was set to a cycle time of 1 ...
The other main method is the use of an “active” device called a CRM (continuous radon monitor). These are mostly used by professional radon inspectors for short-term (48 hours) radon testing during a real estate transaction. There are many different models of CRMs, but they all require ...
Figure 7. A vacuum monitor installed in the vent pipe confirms that the fan is providing the required negative pressure, although further testing is needed to determine whether indoor radon levels have actually declined. Where's the air coming from? That was quite a strong airflow, but a sing...
