background:  the aim of the study was to estimate the radiation dose during emergency exposure to patients treated with iodine-131 during the isolation period. materials and methods: the dose rate from a sample of 192 patients administrated by three different radioactivity of 131i (3.7, 5.55 and 7.4 gbq) was measured, at 1 meter after 1, 24 and 48 hours post dose administration, at three differ...

Radioimmunotherapy is a recently approved treatment modality for non-Hodgkin's lymphoma that enables physicians to target cytotoxic localized radiation to tumor sites without using external-beam sources. Because it uses a pure beta emitter for therapy, (90)Y ibritumomab tiuxetan can be safely and routinely administered in an outpatient procedure, with few discharge instructions, and minimal ris...

Radioimmunotherapy is a new cancer therapy that combines the cytotoxicity of radiation with the tumor-specific targeting of monoclonal antibodies. Yttrium 90 (Y-90) ibritumomab tiuxetan (Zevalin, IDEC Pharmaceuticals Corporation, San Diego, CA) is indicated for the treatment of patients with relapsed or refractory low-grade, follicular, or transformed B-cell non-Hodgkin's lymphoma (NHL), includ...

Balloon brachytherapy is a technique for the removal of a brain tumor in which an inflatable balloon is placed in a resection cavity and then filled with liquid I, delivering low energy dose to the cancerous cells surrounding the cavity. After preparing a patient room to mitigate any spills or contamination, liquid 125I (Iotrex) was assayed with a dose calibrator and injected into the balloon p...

Background: This study is conducted with the aim of determining the knowledge, attitude and behaviors of the personnel on radiation safety, who are exposed to radiation and working in a university hospital in Istanbul.  Materials and Methods: In this research, which is descriptive, a questionnaire that consists of 20 questions conducted to 101 healthcare personnel who are working with radiation...

background: recently, there have been many studies on the harmful effects of radiation and the regulations on radiation safety have been toughened both at the in nation and abroad. this study aims to identify the perceptions and actions taken as to radiation safety, and the degree of knowledge related to radiation held by the radiologists working in large hospitals. materials and methods: the r...

conclusions portable radiological examinations did not expose healthcare providers to high doses of ionizing radiation. nurses’ radiation protection knowledge was limited and hence, they require in-service education programs. results the mean of participants’ radiation protection knowledge was 4.77 ± 1.38. the most prevalent radiation protection behavior of nurses was leaving the intensive care...

OBJECTIVE There is considerable variation in the national regulations of different countries for the release of patients from hospitals after radioiodine therapy. Individual variations make these practices, when based on the worst case scenarios, too restrictive for the majority of patients. However, there are cases in which strict rules are needed to comply with the dose limits to other indivi...

BACKGROUND Radiation safety is an essential component in the treatment of patients with thyroid diseases by ¹³¹I. The American Thyroid Association created a task force to develop recommendations that would inform medical professionals about attainment of radiation safety for patients, family members, and the public. The task force was constituted so as to obtain advice, experience, and methods ...
