The LET refers to the linear energy transfer, the amount of energy transferred by ionizing radiation per unit length of tissue traveled. LET is variable between radiation types. High-ionization radiation, including neutrons and alpha particles, cause more biological damage than radiation with a lower LET, including x-rays and gamma rays.

Skin injuries are a result of the dose to the skin. Dose represents the energy deposited per gram of tissue, which can also be measured as Kerma kinetic energy released in matter. Kerma in air can be converted to dose in soft tissue using numerical constants.

Multiple-choice exams are used frequently in medical education. They are reliable and allow for rapid marking and immediate feedback for students. The three basic levels of learning are knowledge, combined comprehension and application, and problem solving.

Test your Dental Radiograph Knowledge! Phosphor plate receptors have greater latitude than traditional film and solid-state rigid-wired or wireless sensors. Latitude refers to the ability to capture a diagnostic image with a range of exposures. Advantages of phosphor plate receptors over solid-state sensors and traditional film are their flexible construction, greater active area of exposure, and lower retake frequency. These advantages help reduce exposure-related retakes. Disadvantages of phosphor plate receptors include the risk of creasing or scratching which can result in image artifacts and the need for replacement.
