“…Studies that have been conducted among radiology personnel 16,17 have shown that they possess inadequate knowledge about radiation protection. Hobbs et al 18 conducted studies among healthcare providers who belong to multiple departments and found that their knowledge about radiation exposure and risk was poor at baseline but had significantly improved after participation in a brief educational presentation. Another study that was conducted among the physicians, interns, and radiologists of a hospital in Hong Kong 19 found that all three groups demonstrated very poor levels of knowledge about radiation protection.…”

Background: The use of medical radiation in diagnosis and procedural and surgical treatment is increasing. Therefore, healthcare personnel should be adequately aware and knowledgeable about radiation hazards to protect themselves and their patients from its adverse effects. The objective of this study was to examine awareness about radiation hazards and knowledge about protection methods among the anesthesia personnel and surgical subspecialists of a quaternary care academic center. Methods: A validated questionnaire was completed by anesthetic personnel and surgical subspecialists. It consisted of questions that required demographic information and assessed awareness about radiation hazards. In addition, 15 multiple-choice questions assessed knowledge about radiation across the following domains: the main principle of radiation protection, personal annual radiation dose, personal protection equipment, safe distance from an X-ray machine, and susceptible organs. Results: A total of 270 potential participants were emailed and invited to respond to an online questionnaire, and the response rate was 79.3%. Of the 214 participants, 69.2% were women; the mean age of the sample was 34.8 years. Most of the participants (63.1%) considered radiation exposure that occurs as a part of daily work to be very harmful; 86.4% and 78.5% reported that they always wore a lead apron and a thyroid shield when working in an environment that entails radiation exposure, respectively. The mean score for knowledge about radiation hazards and protection was 6.4 ± 2.0 (maximum possible score = 15) Therefore, there is a need to improve anesthetic personnel and surgical subspecialists’ knowledge about radiation protection, especially with regard to the use of lead goggles and harmful doses of radiation. Conclusion: The present findings suggest that there is a reasonable level of awareness but a relative lack of knowledge about radiation hazards and protection among anesthesia personnel and surgical subspecialists. Therefore, continuing medical education on radiation hazards and protection must be mandated.

“…83 However, CT requires a large set of projection data and high radiation dose to achieve sufficient image quality. It is estimated that up to 2% of cancer cases are the result of the radiation obtained from CT imaging, 84,85 thus this risk potentially negates many of the benefits. XACT takes advantage of high sensitivity to x-ray absorption and high ultrasonic resolution in a single modality.…”

Ionizing radiation‐induced acoustics for radiotherapy and diagnostic radiology applications

Acoustic waves are induced via the thermoacoustic effect in objects exposed to a pulsed beam of ionizing radiation. This phenomenon has interesting potential applications in both radiotherapy dosimetry and treatment guidance as well as low-dose radiological imaging. After initial work in the field in the 1980s and early 1990s, little research was done until 2013 when interest was rejuvenated, spurred on by technological advances in ultrasound transducers and the increasing complexity of radiotherapy delivery systems. Since then, many studies have been conducted and published applying ionizing radiation-induced acoustic principles into three primary research areas: Linear accelerator photon beam dosimetry, proton therapy range verification, and radiological imaging. This review article introduces the theoretical background behind ionizing radiation-induced acoustic waves, summarizes recent advances in the field, and provides an outlook on how the detection of ionizing radiationinduced acoustic waves can be used for relative and in vivo dosimetry in photon therapy, localization of the Bragg peak in proton therapy, and as a low-dose medical imaging modality. Future prospects and challenges for the clinical implementation of these techniques are discussed.

“…Therefore, the issue of medical radiation not only affects the welfare of medical professionals and patients, but the entire environment and the welfare of people globally. Importantly and surprisingly, the level of radiation exposure knowledge is relatively low for medical diagnostic imaging amongst both the medical professionals, patients and the general public, based on accumulating lines of evidence, i.e., multi-nations (US and Finland) cross-section surveys [6][7][8]. In clinical practice, low back pain is the most common…”

Modern medical imaging facilitates the diagnosis and treatment of human diseases. However, few people are aware of the cons of radiation exposure from medical imaging. Emerging evidence reveals that cumulative doses of radiation exposure will increase the morbidity and mortality of pertaining cancer. As a special young population, patients with adolescent idiopathic scoliosis (AIS) suffer more radiation harms from repeated diagnostic imaging, most of which can be avoided in clinical practice. Accumulating evidence highlights reduced cancer risks of radiation exposure for AIS patients with low/zero radiation imaging modalities proposed, amongst which easy conversion from anterior-posterior (AP) to posterior-anterior (PA) projection for whole-spine radiographs should be stressed. It can greatly reduce radiation doses without compromising the quality of diagnostic imaging. Tight collimation combined with PA projection can further reduce radiation harms, and need to be spread to benefit people globally.
