Despite the use of ionizing radiation and most of the harmful effects commonly known but not shown, insufficient attention has been observed for radiation protection. Radiation-exposed patients, physicians, health care team and staff should receive training in this field. The aim of this study is the doses of radiation in the operating room to identify and inform health personnel in radiation protection. Radiation exposure to operating room staff (doctor, nurse, medical staff, X-ray technician, anaesthesia technician, etc.) has been recognized as a necessary hazard in operating room. The purpose of our work is to determine operating room staff radiation doses for operating room to identify procedures associated with higher radiation doses, and to determine the effects of various parameters on staff doses. This study was performed at Suleyman Demirel University Medical Faculty Hospital. The procedure of study was performed in department of anaesthesia. We recorded that radiation doses data include all related imaging performed as part of department procedure. The distances were 100, 150, 250 cm from X-ray tube. It is important to understand that radiation affects medical staff in operating procedures. Use of low doses of ionizing radiation does not have knowledge of the long-term results but we need to be careful to conclude that use of radiological protection. During radiation protection, the maximum dose, even under the thick, the minimum degree of exposure to radiation is an important factor for our health. In addition, in the study, Philips BV-25 Gold is used as a brand fluoroscopic device. Device, 1.2-2 kV, 60-100 mA/s of doses between the values.

Cancer is one of the most deadly diseases posing threat for our health. The most important method for eradicating of cancer cells is photoradiotherapy. Electrons accelerated by the accelerator are converted to photons in the process of bremsstrahlung. These photons are focused on diseased cells. Photon leaving accelerator head should assure a given dose intensity in cancer cells. Measuring of beam parameters at apparatus output is essential to determine the dose. In this study, Suleyman Demirel University research and education hospital in radiation Oncology department which has located at 18 MeV accelerator in energy gamma dose was measured.

Computed tomography is an imaging process that uses x-ray equipment to create detailed scans, of areas inside the body. A picture created during computed tomography process shows the organs, bones, and other tissues in a thin "slice" of the body. Computed tomography is used in cancer diagnosis in many different ways to detect abnormal growths, helps to diagnose the presence of a tumor, provides information about the stage of cancer, determines exactly where to perform a biopsy procedure. The x-rays, gantry around the head, chest or another body part, helps to make a three-dimensional image that is much more detailed than pictures from other x-ray machines. Computed tomography imaging involves the use of x-rays, which are a form of ionizing radiation. Exposure to ionizing radiation is known to increase the risk of cancer. The aim of this study was to assess the radiation exposure received during computed tomography in a representative sample of patients.

Cancer is one of the main disease to threat for human health. Besides surgery and medical treatment (chemotherapy), radiotherapy is commonly used treatment method to kill cancer cell. For this method high energy photon is required. Clinic Lineer Accelerator (cLINAC) relatively lower energy than other LINAC has been used to obtain photon via bremsstrahlung processes. When accelerated electron beam impinges to the thin target bremsstrahlung occurs and photon can be created. Those photons can be focused on cancer cell and kill cancer. In order to focus photon beam collimator materials in LINAC head generally contains heavy elements is used and the interaction of bremsstrahlung photon with the such heavy nuclei the neutron can be produced inside the treatment rooms. The threshold of the neutron production for those materals is about 10 MeV. As the neutron is more dangerous than photon it is important to determine neutron dose during radiotherapy treatment. In this study neutron dose rate has been measured and simulated in radiotherapy room.
