Measuring Radiation

Radiation with enough energy to cause changes at the atomic level is called ionizing radiation. It can damage cells, so it is important to measure its potential health effects – but how? Units measuring ionizing radiation are commonly named after leading physicists in the field. Scientists now use Becquerel, Gray and Sievert to quantify radiation and estimate its impact on people.
