What is the effective dose limit for a radiographer over any given 13-week period?

The effective dose limit for a radiographer over any given 13-week period is typically set at 3 rem (30 mSv). This limit is established by regulatory bodies such as the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP) to ensure the safety of healthcare workers who work with ionizing radiation.

These dose limits are designed to minimize the risk of radiation-induced health effects while allowing professionals to perform their duties effectively. The 3 rem limit acknowledges that while radiographers may be exposed to radiation in their everyday work, there are safety measures and regulations in place to keep these exposures as low as reasonably achievable (ALARA principle).

Other potential choices indicate limits that either exceed or fall below the recommended safe exposure threshold established for radiographers, which is why they are not the correct answer in this context. Understanding these limits is crucial for radiographers to maintain their health while providing essential imaging services.
