What effective dose limit should be applied for personnel monitoring in radiography?

In the context of personnel monitoring in radiography, the effective dose limit of 5.0 rem (0.05 Sv) is established based on guidelines set by regulatory bodies such as the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP). This limit is designed to ensure that radiation exposure to individuals working in radiography remains within safe levels while still allowing for the essential work activities associated with the field.

This limit accounts for both stochastic and non-stochastic effects of radiation exposure, balancing the need for occupational safety with the operational requirements of radiographic procedures. It recognizes that some risk is acceptable in occupational settings provided it is kept within defined boundaries to protect workers' health.

Knowing this, the other proposed limits (1.0 rem, 0.5 rem, and 2.0 rem) fall below this standard for effective dose limits and would not provide adequate protection for individuals who might be exposed to radiation during their work in radiography. The choice of 5.0 rem allows for some flexibility in exposure, addressing the reality of varying workloads and responsibilities in radiological practices.
