What should a radiology staff do in order to protect the patient from unnecessary exposure to radiation?

Use proper shielding (lead apron, lead glass, thyroid shield and goggles. Move away from the source if your presence is not necessary. Anybody not needed during a procedure should stay outside the interventional radiography.

How do you protect a patient from radiation exposure?

In general, alpha, beta, gamma and x-ray radiation can be stopped by:

  1. Keeping the time of exposure to a minimum,
  2. Maintaining distance from the source,
  3. When appropriate, placing a shield between yourself and the source, and.
  4. Protecting yourself against radioactive contamination by using proper protective clothing.

What are the three principal methods used to protect radiographers from unnecessary radiation exposure?

The three major principles to assist with maintaining doses “As Low As Reasonably Achievable” are time, distance and shielding.

What are the basic protective measures that can be used to minimize radiation exposure?

To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.

What material can protect you from radiation?

This is why lead aprons and blankets are the most effective shielding material to fight off x-rays and gamma-ray. After all, lead has a very high number of protons in each atom (82 to be specific), which makes it a very dense metal shield.

What materials can block space radiation?

The most penetrating ionizing radiation (gamma rays and galactic cosmic rays) can pass through aluminum but is stopped by thick and dense material such as cement.

What are three methods of reducing a patient’s exposure to ionizing radiation?


  • Minimize time spent in areas with elevated radiation levels. Minimizing the exposure time reduces a worker’s dose from the radiation source.
  • Maximize distance from source(s) of radiation. …
  • Use shielding for radiation sources (i.e., placing an appropriate shield between source(s) of radiation and workers).

What are the main principles involved in radiation exposure?

For reducing radiation exposure, there are 3 principals: time, distance, and shielding.

  • Time. Radiation exposure can be accumulated over the time of exposure. …
  • Distance. A greater distance from the radiation source can reduce radiation exposure. …
  • Shielding.

How can I reduce my phone radiation?

What sources of background radiation are most difficult to avoid?

The major natural radionuclides of concern are thorium-232 (232Th) and uranium-238 (238U) and their decay products, as well as potassium-40 (40K). Thorium and uranium primarily undergo alpha and beta decay and are not easily detectable.

What is the most radiation resistant material?

Materials like PEEK and polyimide show good resistance against gamma radiation and X-rays. By contrast, PTFE and POM are very sensitive and are therefore less suitable for applications that involve exposure to radiation.

Does gold absorb radiation?

First, gold is capable of absorbing radiation at a significantly higher rate than tissue: up to about 100 times more for keV energies (2). Second, gold nanoparticles that interact with radiation can release extra electrons via the Auger effect.
