    Opis:
    The aim of this study was to assess the radiation dose received by doctors, nurses, X-ray technician medical staff during cardiac catheterization in a representative sample of the staff in our angiography department. Radiation from X-ray machines can cause serious side effects. Radiation exposure of angiography staff (doctors, nurses, medical staff and X-ray technicians) has been recognized as a necessary hazard in angiography department. The purpose of our work is to determine angiography staff radiation doses during interventional radiology, 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 an interventional radiology department. We have recorded radiation doses data during all related imaging procedures performed as a part of department activity. The distances from the X-ray tube were 0 cm (doctor), 60 cm (nurse), 120 cm (medical staff) and 180 cm (X-ray technician). It is important to understand the radiation effects on medical staff in interventional radiology procedures. Determinants of radiation risk include not only radiation dose levels but also medical staff number, ages, gender and their position. These factors can increase or decrease the risk of exposure.

    Opis:
    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.

    Opis:
    The radiation is used in a wide range of medical fields, in diagnosis and treatment. Certain body parts, like thyroid, are more specifically affected by exposure to different types of radiation sources. The thyroid is highly susceptible to radiation carcinogenesis and exposure to ionising radiation is the only established cause of thyroid cancer. In this study, we have examined radiation doses measured during diagnosis which used dental panoramic radiography. The measurement has been performed in the Suleyman Demirel University, at PlanmecaProMax 3D (cone beam) imaging unit. The device operates at 66-70 kV, 8-10/22 mA/s.

    Opis:
    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.

    Opis:
    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.

    Opis:
    Nuclear medicine is great for viewing the roles of body organs. Medical imaging in nuclear medicine takes radioactive pharmaceuticals and studies their path of progress through patient's body. The principles of nuclear medicine are different from those of diagnostic radiology. The nuclear medicine can study the functioning of body and how it actually works. On the other hand, usage of different kinds of radiopharmaceuticals in nuclear medicine examinations can affect the dose rates. The purpose of our investigation was to estimate the effective dose from most common procedures, performed in nuclear medicine departments. We noted the injection radiation doses, which are used for diagnosis in nuclear medicine clinics. Later patient radiation doses were calculated, according to models recommended in ICRP 106.

    Using bremsstrahlung photon is one of the principal means to treat cancer. Bremsstrahlung photons are created in medical LINAC and the interaction of bremsstrahlung photon with the heavy nuclei that constitute the linac head shielding is the main process of neutron production 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. The neutron distribution depends on some parameters such as gantry angle. In this study neutron dose rate has been simulated as a function of gantry angle.
