Why is ALARA important in radiology?
Rest assured that there is an ALARA principle in place for minimizing radiation exposure, which stands for As Low As Reasonably Achievable, to help limit the dosages of radiation exposure. This is a best practice in addition to being predicated on legal doses that are in place for all radiation safety programs.
What are the three basic rules of radiography?
Three basic principles should be adhered to when dealing with radiation and making radiographs: • Time • Distance • Shielding. These principles form the basis of a broader radiation safety concept called aLaRa (as Low as Reasonably achievable).
How is ALARA achieved?
The ALARA goal is best achieved when taking three important elements into consideration: time, distance and shielding, notes University Medical. Reduce the time exposed when possible. Double the distance between your body and the source of radiation to cut the exposure by a factor of four.
What is 10 days rule in radiology?
The guiding principle is the 10-day rule stating that the abdominal area (lumbar spine, pelvis, coccyx, and hips) should not be irradiated after the 1st 10 days of one’s menstrual cycle.
Who does ALARA apply to?
As low as reasonably achievable (ALARA) is a principle of radioprotection stating that whenever ionizing radiation has to be applied to humans, animals or materials exposure should be as low as reasonably achievable.
Why is ALARA principle important?
ALARA (As Low As Reasonably Achievable) is a safety principle designed to minimize radiation doses and releases of radioactive materials. More than merely best practice, ALARA is predicated on legal dose limits for regulatory compliance, and is a requirement for all radiation safety programs.
Why is Alara important?
What is the difference between radiology and Radiography?
Radiology encompasses not only imaging techniques, such as x-rays, but also treatments, such as radiation therapy. Radiography is limited to performing the actual imaging tests. These tests are X-rays, CT scans and MRI procedures.
Why is ALARA important?
Who established ALARA?
ICRP
In its 1990 Recommendations [3], ICRP introduced the current wording of the optimisation principle, known as the “ALARA” principle – As Low as Reasonably Achievable. The acronym “ALARA” has been used for more than 20 years by radiation protection professionals.
What is 28 day rule in radiography?
Based on this, it was suggested to do away with the 10-day rule and replace it with a 28-day rule. This means that radiological examination, if justified, can be carried throughout the cycle until a period is missed. Thus the focus is shifted to a missed period and the possibility of pregnancy.
What is 28 day rule in radiology?
What is the ’28 Day rule’? Whereas the 28 day rule, is for radiological examination that can take place throughout the cycle of 28 days until a patient experiences a missed period and suitable for low dose radiological examination (chest x-ray).
