What functionality does the SAM-940 provide for isotope identification?

The correct answer emphasizes the importance of rapid calibration with various sources, which is a significant feature of the SAM-940. This functionality ensures that the device can quickly and efficiently adapt to different types of radiation sources, allowing for accurate measurements and identification of isotopes. Rapid calibration is essential in practical applications, especially in environments where quick decision-making is crucial, such as emergency response situations or field measurements.

This capability enhances the usability of the SAM-940 by making it versatile and efficient, providing the operator with the ability to obtain reliable readings without extensive setup time. The ability to swiftly calibrate with a range of sources allows the user to focus on identifying isotopes rather than being hindered by complex calibration processes.

In comparison, while features like multi-detection capabilities, adjustable sensitivity settings, and pre-programmed isotope databases are advantageous in their own right, they do not directly address the speed and efficiency of adapting to different isotopes as effectively as rapid calibration does.
