Is the statement "The equipment required for radon decay product concentration determination by GW consists of an air sampling pump capable of maintaining a flow rate of 2 to 25 liters per minute through the selected filter" true or false?

The statement is true because the determination of radon decay product concentration in groundwater (GW) requires specialized equipment designed to accurately measure the presence of these decay products. An air sampling pump is essential for this process, as it collects air samples that can contain radon decay products. The specified flow rate of 2 to 25 liters per minute is crucial for ensuring that the air samples are representative and that sufficient volume is collected for accurate analysis. This range of flow rate allows for effective air sampling while minimizing the disturbance of the air flow, which is necessary for reliable measurements.

In summary, the correct statement reflects the technical specifications needed to properly measure radon decay products, affirming that the equipment and flow rate mentioned are indeed vital for accurate determination in radon measurement practices.
