For Neutron Dosimeters, where should it be worn?

• A. On the ankle
• B. On the head
• C. On the midsection, flat against the body
• D. On the shoulder

Answer: (C)

Placing the neutron dosimeter at the midsection, flat against the body, gives a reading that best reflects the average whole-body neutron exposure. Neutrons interact with tissue and clothing, and the body itself acts as a moderating and shielding medium. Positioning the dosimeter at the midsection keeps it close to the body’s center of mass, minimizes air gaps that can alter readings, and reduces variations caused by posture or limb shielding. Locations at the ankle or head would experience a different neutron flux and shielding, leading to readings that don’t represent overall exposure, while a position on the shoulder can be affected by neck-related scattering and less representative of whole-body dose. So, the midsection, flat against the body, is the most reliable choice.
