How is Radiation Measured?

The majority of scientist use the System Internationale or SI. This is a uniform system of weights and measures the evolved from the metric system. Here in the US the conventional method of measurement is still used, on the most part. To determine the amount of radiation emitted by a radioactive material is measured by the conventional unit ‘curie’ (Ci). This was name of course for Marie Curie. Or the SI unit becquerel (Bq). Radiation absorbed by a person is measured using the conventional rad unit or the SI unit gray (Gy). Biological risk of exposure to radiation is measured using the conventional rem unit or the SI unit sievert (Sv). Look here for more information:
