Radiation Protection for Healthcare Workers

The International Commission on Radiological Protection (ICRP) and other organizations have worked diligently to investigate and educate scientific and regulatory agencies about the benefits and risks of ionizing radiation. The guidelines and recommendations created by the ICRP form the basis for radiological protection in Canada and most other developed countries. Exposure to ionizing radiation is monitored for healthcare workers and rules and regulations have been established that guide the use of protective clothing, shielding, and the safe acquisition of images for workers and patients. (4) Facilities that administer radiation for diagnosis are regulated by provincial and federal agencies that oversee the safe and appropriate use of this diagnostic tool. These rules and regulations govern the assessment and maintenance of equipment, the radiation dose administered by this equipment, the monitoring of radiation exposure for patients and medical staff, and the proper protection o...

Measurement of Radiation

Radiation exposure can be measured and monitored. The exposure measurement, using the systeme international (SI) units, is determined by the Coulombs/kilogram (C/kg). However, this is a measurement of the administered dose when all of the x-rays are stopped by air not by human tissues. In an attempt to correlate the biologic effects of the radiation absorbed in human tissues one can use an assessment of absorbed dose per unit of mass called the gray. One gray = 1 Joule/kilogram of absorbed radiation. This absorbed dose is different for different tissues in the body i.e. fat absorbs less of the administered x-ray dose than bone. As tissues absorb x-rays differentially and human tissues have different potential for experiencing damage from x-rays i.e. the gonadal tissues are more at risk for radiation damage than are muscle cells, Thus, the concept of dose equivalency has been developed. The most common derived unit of ionizing radiation that can be used to assess the health effect...

Overcome Key Challenges and Improve Safety in Radiology

By Frank Mazza, MD While radiologic procedures are improving patient care in the United States and around the world, the complexity of these procedures, including the use of high-alert medications and the risk of communication failures during handoffs, may contribute to medical errors. The risk of error is especially evident in cardiac catheterization and endoscopy laboratories, radiology, and other imaging settings where health care practitioners may administer medications such as contrast media, adjust rates of IV fluids, and flush IV access lines. Radiology errors pose yet another level of challenges for hospitals and providers operating in the new health care reform environment: Payments have become increasingly and explicitly linked to a complex myriad of performance measurements, and nonperforming providers face greater financial risk. Tackling these payment obstacles often requires a transformation of clinical operations within the radiology department and the establishment...
