What is the measuring range capability required for a survey meter?

The measuring range capability of a survey meter is crucial for effectively assessing radiation levels in various environments. The choice of a range like 2 to 1000 mR/h is essential as it encompasses a wide spectrum of radiation intensity that a survey meter may encounter. This range is sufficient to detect low radiation levels, such as those found in background radiation, as well as higher levels that could be encountered in certain occupational or emergency situations.

Having a lower limit of 2 mR/h allows the survey meter to effectively monitor ambient radiation and identify potential hazards without being limited to higher readings. Additionally, the upper limit of 1000 mR/h ensures that the device can still function accurately in environments where radiation levels may surge, such as near medical facilities or during decommissioning of nuclear sites.

This versatility makes the range from 2 to 1000 mR/h an optimal choice for a survey meter, allowing users to ensure safety across a variety of scenarios, including both routine monitoring and exposure assessment. It strikes a balance between sensitivity to low radiation levels and the capacity to handle potentially hazardous situations.
