Which risk increases when a radiation detector's high-voltage supply fluctuates?

💡 Explanation

Dark current increases because, with higher voltage, electrons overcome potential barriers more easily in the photomultiplier tube's dynodes during radioactive decay. Therefore, spurious counts increase, rather than changes affecting energy spectra because it is a noise floor.
