How is the Sievert defined in terms of REM?

1 Sv = 10 REM
1 Sv = 1000 REM
1 Sv = 100 REM
1 Sv = 50 REM

The correct answer is: 1 Sv = 100 REM

The Sievert is the SI unit used to measure the biological effect of ionizing radiation, specifically focusing on its health impact. It quantifies the dose absorbed by human tissue, adjusted for the type of radiation and its effect on biological systems. To understand the relationship between the Sievert and REM (Roentgen Equivalent Man), it's essential to know that both units are used to quantify radiation dosage but in different systems of measurement. One Sievert is defined as being equal to 100 REM. This conversion reflects a standardization for consistency in the evaluation of biological effects from radiation exposure, ensuring that the units are practically applicable in health physics and radiation safety practice. Thus, recognizing this relationship is crucial for professionals working with radiation, as it assists in the proper assessment of risk and implementation of safety measures when dealing with radioactive materials.
