What is the equivalent of one Sievert (Sv) in rem?

One Sievert (Sv) is equivalent to 100 rem because the rem is a traditional unit of radiation dose in the United States, while the sievert is the SI (International System of Units) unit used internationally. The relationship between these two units is established based on the biological effects of radiation, where 1 Sv is defined as having the same biological effect as 100 rem.

This conversion is essential for understanding radiation doses in different contexts and ensures consistency in measuring health risks associated with various levels of radiation exposure. The rem is often used in the context of medical and occupational exposure, while the sievert is more common in scientific and environmental research.

By recognizing that 1 Sv equals 100 rem, professionals in the field can accurately communicate and assess the implications of radiation exposure, ensuring better safety practices and regulatory compliance. The other choices reflect ratios that do not align with the established conversion, which is firmly rooted in the scientific understanding of radiation dose metrics.
