ALARA translates as "As Low As Reasonably Achievable" and not only needs to be an integral part of all tasks that involve the use of radiation or radioactive materials but also used as the guiding principle to stay consistent with the purpose for which the activity is undertaken.

There are three major principles that assist in maintaining ALARA and can help prevent both unnecessary exposure and overexposure: time, distance and shielding.
- Time: Minimize the time spent near a radiation source to only what it takes to get the job doneDistance: maximize your distance from a radiation source as much as you can. The greater the distance, the lower the doseShielding: put something between you and the radiation
source.
A common example of how these three principles work together is an x-ray a doctor’s office. The radiation technician goes behind a barrier while taking the x-ray image to protect them from the repeated daily exposure to radiation.
“Not long after the discovery of ionizing radiation, it became clear that exposure to high doses of such radiation was detrimental to human health. After the bombings that ended World War II, the United States moved toward further investment in both nuclear weaponry and nuclear energy for civilians. The Nuclear Regulatory Commission, laid out increasingly stringent safeguards to protect both civilians and nuclear workers. This effort culminated in the ALARA (As Low As Reasonably Achievable) protocol, which eventually became adopted as the gold standard of nuclear safety.”
Michael Baumer, March 14, 2015 (://large.stanford.edu/courses/2015/ph241/baumer2/)
ALARA insures that any work with ionizing radiation or radioactive materials is consistent with the purpose for which the licensed activity is undertaken and that all safety precautions are taken to protect workers.

Embracing ALARA to Minimize Radiation Exposure
Embracing ALARA to Minimize Radiation Exposure
Ensuring a patient’s exposure to ionizing radiation is “As Low As Reasonably Achievable” (ALARA) while providing the highest quality diagnostic image requires a delicate balance and is the focus of radiation protection programs nationwide. ALARA is a universally accepted principle for limiting the dose to reduce the exposure to ionizing radiation. This tenet assumes that there is no “safe” dose of radiation and is an application of the Linear No Threshold Hypothesis.
Most scientists and standard-setting bodies feel that there is actually a safe dosage level of radiation. However, ALARA urges doses below the safe limits when reasonably possible. ALARA is not a defined dosage level but rather a goal. According to Plexus-IEM, a radiation-related consulting organization, “The ALARA radiation safety principle is based on the minimization of radiation doses and limiting the release of radioactive materials into the environment by employing all ‘reasonable methods’ ALARA is not only a sound radiation safety principle, but it is a regulatory requirement for all ‘radiation protection programs’.”
Time, Distance and Shielding
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 toàn thân and the source of radiation to cut the exposure by a factor of four. Use lead protections such as aprons, mobile shields, glasses and barriers.
RadSite’s commitment to ALARA
According to RadSite’s Chief Medical Officer, William Orrison, Jr., MD, MBA, limiting the radiation dose as much as is possible can reduce cancers by half. And yet the U.S. medical radiation exposure is six times what it was in 1980. Dr. Orrison maintains that medical diagnostic imaging in general is very helpful, and that, in fact, CT scans have prevented more unnecessary surgery than perhaps any technology ever invented. However, because CT scans deliver relatively high doses of ionizing radiation, Dr. Orrison urges administering only necessary tests and if X-rays or CT scans are necessary, getting the right test the first time.
RadSite believes that it is important to reduce dosage levels if possible. At the same time, it is important to maintain perspective. CTs do save lives and reduce unnecessary surgeries. In the best interest of patients, there is a compelling need for consistent quality standards for diagnostic imaging across the U.S.
Accreditation programs such as RadSite foster quality standards and provide education about best practices. One of the many services we provide are educational webinars. We recently hosted a webinar about patient safety and radiation. Click here to view the recording of the session, Patient Safety in Medical Imaging, hosted by Dr. Orrison, to learn about his – and RadSite’s – concern for proper, mindful dosage levels. Dr. Orrison also mentions organizations to join for radiation awareness, such as Image Gently, the Alliance for Radiation Safety in Pediatric Imaging that promotes worldwide efforts to improve safe and effective imaging care of children.
Final thoughts | Embracing ALARA to Minimize Radiation Exposure
Although the risk to patients and imaging from medical radiation is often considered low, the need to keep ALARA in mind is important. RadSite’s safety initiatives include a review of radiation safety policies and procedures as well as ensuring that radiation safety educational programs are in place.

For reducing radiation exposure, there are 3 principals: time, distance, and shielding.What is the best way to minimize exposure to radiation?
Time, Distance and Shielding Distance: Just as the heat from a fire reduces as you move further away, the dose of radiation decreases dramatically as you increase your distance from the source. Shielding: Barriers of lead, concrete, or water provide protection from penetrating gamma rays.What are the three ways to control exposure to radiation in the workplace?
You can protect employees from hazardous doses of radiation by taking the following steps:. Limit the amount of time workers spend in areas where they might be exposed. ... . Make sure employees remain a safe distance from radiation sources. ... . Use appropriate shielding to protect employees from radiation..How can the hazard of radiation be minimized?
Keeping the time of exposure to a minimum, Maintaining distance from the source, When appropriate, placing a shield between yourself and the source, and. Protecting yourself against radioactive contamination by using proper protective clothing. Tải thêm tài liệu liên quan đến nội dung bài viết What are 3 minimizing radiation exposure applications?
