Limited Scope of Radiography Practice Exam - Questions with Verified Answers What statements are correct regarding the link between radiation and genetic effects? The link has been demonstrated in animal studies Increased risk to humans cannot be predicted with respect to an individual. The changes in kilovoltage (kVp) will result in the greatest reduction of patient dose, when milliampere-seconds (mAs) is adjusted to compensate for the change Increase kVp by 30% The following image receptor (...

Lesson Description Often the most neglected and misunderstood types of monitoring on hazardous waste sites are radiation hazards and monitoring. Therefore, waste site workers should understand radiation hazards and different types of radiation. This Radiological Hazards lesson introduces radiological hazards to help workers to choose the type of protection necessary for any type of radiation hazard they may encounter in the workplace. It categorizes radiation types and examines radiation dos...

Absorption - When all of the x-ray energy is absorbed by the ejected electron Acute radiation syndrome - Radiation sickness that occurs in humans after whole-body doses of 1 Gy or more of ionizing radiation delivered over a short time; not seen in diagnostic imaging ALARA - Principle that states that rad exposure should be As Low As Reasonably Achievable Anatomic Position - The position in which the patient is standing erect, with the face directed forward, arms extended by the sides wi...

Lead has an action level of 30 micrograms per cubic meter. In the construction industry, the most common route of lead absorption into the body is ingestion. All contaminated clothes that have to be laundered, cleaned, or disposed of should be placed in closed containers and sealed off. There is no material available which can be used as a substitute to Lead. False
