What is the annual dose limit for gonads as recommended by NCRP?

• A. 5 mSv
• B. 50 mSv
• C. 100 mSv
• D. 500 mSv

Answer: (B)

The annual dose limit for gonads, as recommended by the National Council on Radiation Protection and Measurements (NCRP), is set at 50 mSv. This limit is established to protect the reproductive organs from potential harmful effects of ionizing radiation, which can affect genetic material and reproductive capabilities. The NCRP guidelines are formulated based on research regarding the effects of radiation exposure, with an emphasis on minimizing risks to both individuals and future generations.

Other options suggested lower or excessively high dose limits, which do not align with the recommended protective measures for gonadal exposure. By adhering to a limit of 50 mSv, the NCRP aims to balance the necessity of using radiation in medical and research applications while safeguarding patients and personnel from unnecessary health risks.
