How Can A Radiographer Minimize Radiation Exposure To The Patient?

What do radiographers wear to protect themselves?

During these imaging procedures, radiologic technicians leave the room, or stand behind a protective shield, such as a curtain, that is designed to keep out radiation.

Technicians also wear shielding devices, such as lead aprons, gloves, goggles and masks for radiation protection whenever necessary..

Is radiology a safe career?

Myth The radiation associated with radiologic technologist positions is dangerous. Fact The health risks associated with radiologic technology are minimal. Many aspiring radiologic technologists worry that their field of choice may be dangerous, as it involves extensive work with diagnostic imaging equipment.

How can we protect patients from radiation?

Procedure-related:Minimize fluoroscopy time;Use collimation;Take as few radiographic images as possible;Use magnification appropriately;Decrease the patient to image receptor (image intensifier or flat panel detector) distance;Increase the X-ray tube to patient distance;Be aware of tube angulations.

How can scatter radiation be controlled?

The amount of scatter radiation can be reduced in some cases by any of the following methods. By limiting the incident beam of x-rays to as small an area as possible. By using a low rather than a high kilovoltage. By the use of clearing grids which are still referred to as ‘Potter-Bucky’ or ‘Bucky grids’.

What is air gap technique?

The air gap technique is a radiographic technique that improves image contrast resolution through reducing the amount of scattered radiation that reaches the image detector. … The air gap technique is utilized in both plain radiography and mammography.

What are the basic principles of radiation safety?

General principles of radiation protection from the hazard of ionizing radiation are summarized as three key words; justification, optimization, and dose limit. Because medical exposure of radiation has unique considerations, diagnostic reference level is generally used as a reference value, instead of dose limits.

What are the two types of personal dosimetry?

There are two kinds of dosimeters: Passive Dosimeters. Commonly used passive dosimeters are the Thermo Luminescent Dosimeter (TLD) and the film badge. A passive dosimeter produces a radiation-induced signal, which is stored in the device.

What are the 3 basic radiation safety principles?

Three principles for radiation safety: time, distance, and shielding.

Which is an effective technique to minimizing patient exposure?

Beam Limiting Limiting the FOV to the smallest area that fulfills the clinical requirements is an effective method for reducing unnecessary patient exposure. Under no circumstances should an x-ray beam cover an area that is larger than the receptor.

What materials can block radiation?

Non-lead shielding materials are manufactured with additives and binders mixed with attenuating heavy metals that fall into the same category of materials as lead that also absorb or block radiation. These metals may include tin (Sn), antimony (Sb), tungsten (W) bismuth (Bi) or other elements.

How far does scatter radiation travel?

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 scatter radiation caused by?

Scatter radiation occurs when radiation deflects off an object, causing x-rays to be scattered. It is important to keep in mind that scatter radiation has the ability to travel in all different directions. Most of the exposure your medical staff will endure is from scatter radiation.

What is a radiographer salary UK?

As an experienced radiographer you can earn between £28,050 and £36,644 (Band 6). Typical salaries for advanced radiographers are between £33,222 and £43,041 (Band 7), while at consultant level you can earn up to £71,243 (Band 8c).

How can we protect ourselves from gamma rays?

shield need to be about 13.8 feet of water, about 6.6 feet of concrete, or about 1.3 feet of lead. Thick, dense shielding is necessary to protect against gamma rays. The higher the energy of the gamma ray, the thicker the shield must be.

How many rem per year is safe?

OSHA Limits: Whole body limit = 1.25 rem/qtr or 5 rem (50 mSv) per year (approx.

What are the three fundamental approaches to minimizing radiation exposure?

This principle means that even if it is a small dose, if receiving that dose has no direct benefit, you should try to avoid it. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.

How are radiographers protect from radiation?

It is recommended that the radiologists who work in CT fluoroscopy (CTF) should employ lead glasses, thyroid shields, lead aprons, lead gloves, and portable body radiation barriers. They should wear both internal and external radiation badges to monitor their exposure to scattered radiation during the procedures.
