In Germany, X-rays were discovered by Wilhelm Roentgen in 1895 and in 1905 he was awarded the Nobel Prize in recognition of his contributions to physics. After this discovery, the new X-ray technology was quickly applied in clinical medicine. There is no published information documenting the initial use of ionizing radiation in diagnosis in Saudi Arabia, but in 1950 the country began to pay attention to safety and health and established the first public health department in Makah. This was followed by the creation of King Saud's first hospital in Riyadh in 1956 (1). Say no to plagiarism.

(2). The availability of x-ray technology and the volume of medical imaging can vary significantly from country to country. However, in Saudi Arabia, the development of X-ray technology has increased and potentially increased the radiation dose received by patients, causing concern among doctors. and radiophysicists, as well as regulatory bodies such as the King Abdul-Aziz City for Science and Technology (KACST) National Center for Radiation Protection (SNCRP). The relationship between the development of X-ray technology and the increase in dose has also intensified the question of the justification and knowledge of doctors about the dose administered to the patient during radiological examinations. To name a few, the Swedish study estimated that 20% of all multislice CT scans performed in Sweden may not be justified (3). On the other hand, two studies estimating the awareness of doctors revealed a lack of knowledge about the dangers of radiological examinations on their health and on their patients (4, 5). Increasing the dose in patients with growth of optimization of patient imaging (6) carried out in the local area, country or region where they are applied. . DRLs should correspond to median doses representing typical practice for a group of patients for a specific type of examination. Keep in mind: this is just a sample.

Get a personalized essay In 1996, the ICRP defined two principles governing the professional use of radiation sources: optimization and justification of radiology examinations. Optimization implies that exposure of individuals and the population remains as low as reasonably achievable (ALARA). On the other hand, justification implies that any human activity involving the exposure of a patient is justified by the benefits it can bring. (7).
