Interventional procedures in radiology and cardiology are associated with high dose to the patient. Accurate dosimetry is essential calibration of equipment a means provide necessary accuracy assessment. The objective this work investigate performance dosimeters used interventional different standard non-standard X-ray radiation qualities, potential uncertainties related measurements, thus impr...

We describe an optically transparent, laser heated, thermoluminescent glass dosimeter that is used for fiber-optic-coupled remote radiation monitoring. The glass consists of ZnS nanocrystallites embedded in a Vycor glass host, doped with Cu and Nd ions. An 807 nm, 1 W GaAlAs laser is used to rapidly heat microscopic regions, surrounding the Nd ions, in the composite glass to stimulate blue-gree...

OBJECTIVE The purpose of this paper is to show the effectiveness of a new radiation protection method designed to decrease the amount of scatter radiation received by practitioners performing procedures under fluoroscopic guidance. MATERIALS AND METHODS A sterile, disposable, lead-free surgical drape containing radiation protection material composed primarily of bismuth was evaluated for effe...

introduction: patients administered with a therapeutic dose of 131i for thyroid cancer treatment are potential sources of unacceptably high radiation exposure to other individuals, particularly the patient's immediate family members. the aim of this study is to investigate effects of early liothyronine consumption after radio-iodine therapy on accumulated dose and exposure rate in patients with...

It is a common practice to check the performance of a TLD reader by inserting a light source composed of a phosphor mixed with a radioactive material, e.g., 14C . The response to the light source is used as a measure of a) the calibration or long-term stability of the reader and b) the ability of the reader to reproduce a constant signal. Usually the laboratory which measures a wide range of do...
