Orange Badge Practice Exam

The correct choice for measuring neutron radiation is the Snoopy dosimeter. This type of dosimeter is specifically designed to effectively detect and measure neutron radiation, which requires specialized materials or mechanisms that can respond to neutrons, as they do not ionize materials in the same way that alpha or beta particles do.

Snoopy dosimeters utilize either moderated or thermal neutrons to provide accurate readings of neutron exposure, often achieving this through the use of polyethylene or other moderating materials that help slow down the neutrons so that they can be more readily detected.

Other dosimeters, such as thermoluminescent dosimeters and film badges, are primarily used for measuring gamma and beta radiation and may be less sensitive or effective for neutron radiation. Ionization chambers, while versatile in measuring various types of radiation, including gamma and x-rays, typically require additional components to adequately measure neutron radiation. Thus, Snoopy dosimeters are the appropriate choice for accurate neutron detection.
