Any radiation detector that uses ionization to create current, or to change the resistance of the material (usually a gas), transfers radiation to electricity. These are not power generators, though. There are indirect methods that are widely used for generating power. One is the radiothermal generator (RTG). It uses radiation (usually neutrons) to directly heat a material, then Peltier devices to take that heat and convert is to electric power. .
