What is the recommended annual dose limit for the skin and extremities of a radiation worker by the NCRP?

The recommended annual dose limit for the skin and extremities of a radiation worker, as established by the National Council on Radiation Protection and Measurements (NCRP), is set at 500 millisieverts (mSv). This limit is designed to ensure that radiation workers are protected from excessive exposure, thereby minimizing the risk of potential health effects associated with ionizing radiation in these specific body areas.

The NCRP guidelines take into consideration the biological effects of radiation on the body, particularly the skin and extremities, which can be more susceptible to damage from high doses. The limit is established based on scientific research and data aimed at safeguarding healthcare workers and others in radiation-sensitive occupations.

Maintaining this limit is essential for occupational safety and health, as it helps to promote a balance between the benefits gained from the use of radiation in various fields, like medicine and industry, and the need to protect workers from undue exposure.
