Xenon gas detectors are known to absorb what percentage of photons that reach them?

Xenon gas detectors are particularly effective in photon detection due to their ability to absorb a significant amount of the incoming radiation. The absorption efficiency of xenon gas typically ranges between 60% to 70% of the photons that reach the detector. This absorption is crucial because it impacts the detector's sensitivity and overall performance in capturing and measuring radiation. The gas's high atomic number contributes to its effectiveness in photon interactions, allowing it to be utilized in various applications, including medical imaging and radiation detection systems.

The reasons for the other options being less applicable include the lower ranges that do not accurately reflect the known performance characteristics of xenon gas. For instance, options suggesting below 60% do not leverage the full capabilities of xenon, while those above 70% may imply a performance that xenon does not consistently achieve. Therefore, the range of 60%-70% accurately captures the absorption potential of xenon gas detectors.
