Fourth, note: the sensor can not be exposed to stiff light! This may have a negative impact on the measurement results. During the measurement, the sensor temperature must be kept in the range of 0-40 C.

Warning: High voltage is generated inside the sensor. Although the high-voltage area is isolated and protected by the shell, the contact area between the measuring chamber and the surface of the main board

The domain can be exposed to high pressure. Hold the sensor carefully!

V. Measurement suggestions:

The sensor provides radon concentration level every hour. Therefore, the first valid data is available after 1 hour of power-on.

According to the high variability of radon in a short period of time, radon concentration data may be affected by serious changes. Therefore, in order to obtain more accurate data, it is recommended to use an average value. The average value will represent the existence of actual radon in a better way than the instantaneous value. For short-term analysis, it is recommended to use at least the average value of continuous measurement for more than 72 hours. For long-term analysis, it is recommended to calculate the average value of 5-7 days or longer, and measure it at least once every quarter.

VI. Judgment of test results:

The measurement results are expressed in Becker, which is expressed as Becker per cubic meter of air (Bq/m3).

Outdoor, the average radon concentration is about 4Bq/m3. The average household radon concentration is 20Bq/m3. For concentrations below 100Bq/m3, the individual risk is still relatively low. However, the risk will increase with the increase of radon level. There is no known "safe" radon concentration, but the lower the concentration you are exposed to, the lower the risk to your health.
