What is a Curie electrometer?
What is a Curie electrometer? The quadrant electrometer is part of a vast family of instruments used to measure electricity. Close-up of the inside of a quadrant electrometer on display at the Curie Museum. To measure the electricity generated by the passing of radioactive rays through the air, Marie and Pierre Curie used a quadrant electrometer. How did the Curie electrometer work? The Curies used this device to measure the activity of a radioactive substance – an important property to quantify as radiation treatments for cancer were developed. They measured radiation by attaching the piezo-electric apparatus and a radioactive source...
