As the presence of indoor air pollution that is hardest to ignore easily, radon is the second leading cause of lung cancer in many countries. Depending on the average radon level in a country, radon is estimated to cause 3% to 14% of all lung cancers. Radon is more likely to cause lung cancer in smokers and is the main cause of lung cancer among non-smokers.

Radon is a colorless and odorless radioactive gas formed by the radioactive decay of the small amount of uranium naturally present in all rocks and soils.
Radon is an intermediate product of radium nuclear decay and is the last element of the noble gas group (He, Ne, Ar, Kr, Xe, Rn), which is also the most important one. It has four isotopes, which belong to three different radioactive series of uranium, actinium and actinium. The corresponding monomers of radon element are radon gas, which is a colorless, odorless and tasteless inert gas with radioactivity. Radon is chemically inactive and does not easily form compounds.

Radon may exist in drinking water and indoor air. Radon in buildings and the soil under our homes is the largest source of radon in indoor air.
Radon is ubiquitous and is formed from uranium in all rocks and soils. In many areas, both outdoors and indoors, radon levels are low and pose little health risk.
Radon enters the home through the following ways: cracks where concrete floors meet walls; gaps in the floor; small holes in hollow brick walls; sump pits and sewers.

In addition, the physical and chemical properties and behavioral characteristics of radon as well as its impact on the environment are gradually understood, and radon measurement gains applications in geological prospecting, earthquake forecasting and other fields.

PTM600-RD radon gas detector is also known as environmental radon detector. The box type portable one can be applied in multiple scenarios, such as construction, soil, mining, indoor, decoration materials and so on.

It is based on the design of pumped electrostatic acquisition energy spectrum analysis method and adopts a new generation of high-sensitivity and high-resolution passivated ion implantable planar silicon detector (PIPS) to capture the changes of radon gas concentration quickly in real time.
