During mobile exams stand atleast 6 feet away and if possible at a 90 degree angle from the radiation source (the patient). During c-arm procedures standing on the side of the image intensifier is safest because there is more scatter produced at the entrance surface side of the patient.

What is the safe distance from radiation source?

That means that as the distance from the source increases, the intensity of radiation decreases. To calculate exposure, the rule to use is that the amount of radiation exposure at one metre from the radioactive source equals the amount of radiation exposure at any distance from the source times the distance squared.

How many feet should you be away from radiation?

Scatter radiation exposure, the most common type of exposure you will receive in diagnostic radiology, is reduced to 1/1000 the exposure the patient is receiving if you stand one meter (approximately 3 feet) from the patient.

What is the minimum safe distance from a source of ionizing radiation during radiography?

It is recommended all surgical personnel during X-ray procedures should stand as far Page 4 away as possible (at least two meters) from the source of the radiation.

How can you protect yourself from scatter radiation?

To protect our patients from scatter radiation, we provide safety items, such as lead vests, which act as a barrier, preventing the radiation from hitting other parts of your body, such as reproductive organs.

What is radiation distance?

“Distance” refers to how close you are to a radioactive source. Maximize your distance from a radioactive source as much as you can. This is an easy way to protect yourself because distance and dose are inversely related. If you increase your distance, you decrease your dose.

Why is distance important in radiation?

Distance: Just as the heat from a fire is less intense the further away you are, so the intensity and dose of radiation decreases dramatically as you increase your distance from the source. Shielding: Barriers of lead, concrete, or water provide protection from penetrating radiation such as gamma rays and neutrons.

What is time distance and shielding?

Time, distance, and shielding measures minimize your exposure to radiation in much the same way as they would to protect you against overexposure to the sun (as illustrated in the figure below):

What are safe radiation levels for humans?

Adult: 5,000 Millirems. The current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is "as low as reasonably achievable; however, not to exceed 5,000 millirems" above the 300+ millirems of natural sources of radiation and any medical radiation.
