The dose a radiographer can receive in one year is?

The accepted dose limit for a radiographer, according to regulations and guidelines such as those from the National Council on Radiation Protection and Measurements (NCRP) and the Occupational Safety and Health Administration (OSHA), is typically set at around 5 rem (or 5R) per year for radiation workers who are in occupations where exposure to radiation is a possibility. This limit is designed to minimize the risk of radiation-related health effects while allowing for a practical level of occupational exposure.

In calculating allowable doses, considerations include factors like longevity, risk levels, and safety standards developed based on extensive research and statistical analysis of radiation exposure effects over time. The goal is to balance the need for radiologists and technicians to perform their jobs effectively while ensuring they remain below thresholds that could adversely affect their health.

The other choices presented do not reflect the established dose limits for radiographers. For instance, a limit of 2R or 8R is not aligned with the regulatory standards, and while 10R exceeds acceptable annual limits significantly. Thus, the choice of 5R is well supported by the scientific and regulatory framework surrounding occupational exposure to radiation.
