Which of the following statements about radiation detection devices is false?

The statement indicating that calibration is not necessary for accurate readings is indeed false because calibration is a vital process for ensuring accurate measurements in radiation detection devices. Over time, various factors such as wear and environmental conditions can affect the performance of these devices. Regular calibration against known standards allows for adjustments to be made so that the measurements reflect the true levels of radiation present. This process is essential to maintain the reliability and accuracy of the readings provided by the devices, ensuring that safety protocols and monitoring practices are effectively upheld.

The other statements are accurate reflections of the characteristics and uses of radiation detection devices. They serve to measure both ionizing and non-ionizing radiation based on their design, are crucial for monitoring individual exposure through personal dosimeters, and include common types like Geiger-Muller counters, which are widely used in various applications for their ability to detect radiation efficiently.
