Three principles for radiation safety: time, distance, and shielding
- 1. Time Radiation exposure can be accumulated over the time of exposure. In C-arm fluoroscopy guided interventions, the time spent checking the C-arm fluoroscopy is related to the radiation exposure. The longer the exposure time, the more radiation exposure to the pain physician. ...
- 2. Distance A greater distance from the radiation source can reduce radiation exposure. ...
- 3. Shielding

Three principles for radiation safety: time, distance, and shielding
2. Distance. A greater distance from the radiation source can reduce radiation exposure. The amount of radiation exposure is not inversely proportional to the distance from the radiation source, but is inversely proportional to the square of the distance [2,4].This means that double the distance from the radiation source can reduce the radiation exposure not to 1/2 but to 1/4.

How to reduce radiation exposure?
A greater distance from the radiation source can reduce radiation exposure. The amount of radiation exposure is not inversely proportional to the distance from the radiation source, but is inversely proportional to the square of the distance [2,4]. This means that double the distance from the radiation source can reduce the radiation exposure not to 1/2 but to 1/4. Therefore, maintaining a greater distance from the X-ray generator is a very effective method for radiation safety. In a previous study of radiographers, two steps behind the mobile support structure can decrease the exposure of the radiographer by about 80% [4]. In another study, being only 20 cm farther from the center of the X-ray field can decrease the radiation exposure by about 73% [5].
What is the C-arm fluoroscopy?
Pain physicians usually use C-arm fluoroscopy for the treatment of patients. The C-arm fluoroscope is an important device for pain interventions. However, pain physicians can be exposed to radiation during use of C-arm fluoroscopy. According to a previous study in Korea, most pain physicians were worried about the adverse biological effects of radiation exposure [1]. However not many pain physicians had knowledge of radiation safety [1,2]. Furthermore, not many pain physicians used radiation protective devices and radiation protective methods [1,2]. Even though almost all pain physicians had used thyroid protectors and aprons, the use of lead glasses and gloves was low. For reducing radiation exposure, there are 3 principals: time, distance, and shielding.
What are the 3 principles of radiation?
Do you want to reduce your radiation exposure? Please remember the 3 principles; time, distance, and shielding.
Can a doctor use a shielding device?
There are many shielding devices such as caps, lead glasses, thyroid protectors, aprons, radiation reducing gloves, and so on, for radiation safety during C-arm fluoroscopy-guided interventions. Even though the protective effect is enough for radiation safety, no use of the devices cannot protect the physician from radiation. In Korea, the use rate of the apron and thyroid protector by pain physicians is over 80% [1,2,6]. However, the use rate of lead glasses was about 40%, and the use rate of radiation reducing gloves was lower than 35% [1]. The radiation shielding devices are expensive, and the use of shielding devices can be uncomfortable. However, when a physician uses these devices, they can be protected from radiation exposure.

What are the tools used to immobilize patients?
Radiologic technologists should ensure individuals present during x-ray operation wear personnel monitors as appropriate. Mechanical holding devices (e.g. compression bands, sponges, sandbags and 2-inch-wide tape) are effective tools for the immobilization of patients and should be used if the procedure permits. Only as a last resort should someone hold the
What is health physics?
Health Physics is concerned with providing occupational radiation protection and minimizing radiation dose to the public. Every technologist has the obligation to always ensure that the radiation dose to both the patient and other health care professionals are kept as low as reasonably achievable (ALARA) without compromising the diagnostic value of the image.
What is the role of a nurse in a surgical procedure?

What is beneficence in nursing?
Beneficence is defined as an action that takes place to purposefully prevent the possibility of any harm that could effect the patient or what actions could improve the patients overall situation by promoting what is best for the patient. This includes spiritual and psychological health as well. Examples are administering vaccination, education on prevention, performing CPR, calming a patient down that is agitated and combative, or even choosing to request pain medication for the patient that doesn’t have a voice. These are act of beneficence. Nonmaleficence requires nurses and all medical staff, to avoid causing purposeful harm to the patient as well as to refrain from any feelings of malice that we might encounter.…
What are the policies of a GP surgery?
There are many policies in place in a GP surgery, I will be talking about; Health and Safety, Confidentiality and Whistle Blowing. These policies are in place to ensure that the GP surgery promotes a positive care environment and promotes service users rights. Health and Safety Health and Safety in a GP surgery is in place to protect the staff and patients from any mistreatments or accidents within and around the surgery. The responsibilities of a health and safety policy are to ensure that the surgery is a safe environment to be in and there are no hazards that could potentially cause accidents to staff or patients. The surgery must ensure that their computer and filing systems with the surgery are safely recorded and kept confidential.…
How to prevent airborne infection?
Preventing infections related to microorganisms that are airborne, bloodborne, or droplets can be done by donning appropriate PPE; such as: surgical or procedural mask, respirator, gloves, long-sleeved gowns and eye protection such as goggles or face shields, and most importantly, washing hands before and after each patient care activity. The rationale behind this is to prevent skin and mucous membrane exposure when in contact with blood and body fluid of any patient and also to decrease risk of nosocomial infection or transmission of infection. Proper handling of infected items is the key to reduce the risk of transmission and cross contamination within the facility. Removal of gloves, masks, and gowns after each use should be disposed according to the facility…

What are the principles of radiation?
The first of these principles is that no human should be exposed to doses of radiation – in the workplace or otherwise – unless it is going to do more harm than good. This includes: 1 Any time a new source of radiation is discovered, used, or implemented 2 Any time a new activity arises that puts people at risk via their occupation (as is the case for pilots or astronauts) 3 The use of those sources are proven to be of reasonable benefit for the individual (as is the case where x-rays, CT and PET-CT equipment is used) or for society as a whole
What is the first principle of radiation exposure?
In every case of radiation exposure in the work place, the goal is to minimize the time an employee, patient or bystander is exposed to radiation. By minimizing the amount of time an individual is exposed to radiation, you simultaneously minimize the total radioactive dosage their bodies absorb.
What is Lancs Industries?

We design and manufacture radiation protection and shielding products of all types, and we’re also happy to create custom gear for virtually any application.
How to minimize occupational radiation exposure?
Controlling and minimizing occupational radiation exposure is largely done via time constraints (setting specific time limitations on an employee’s ability to work in a certain space or in the field of a specific element or object) and by providing proper, industry recognized radiation protection and shielding.
Is radiation the largest source of man-made radiation?
However, radiation experts agree that, “…radiation doses from medical exposure are now the largest source of man-made radiation exposure.”. If you work in a career that poses a risk of radiation exposure, it’s essential that you learn and adhere to three, key principles.
Is radiation measurable?
The good news about radiation is that it’s measurable via the assistance of a dosimeter. This allows Radiation Safety Officers and individual employees the ability to precisely monitor radiation exposure at any given time.
Should humans be exposed to radiation?
The first of these principles is that no human should be exposed to doses of radiation – in the workplace or otherwise – unless it is going to do more harm than good. This includes:
