PURPOSE To determine whole body and hand radiation exposure to the hand surgeon wearing a lead apron during routine intraoperative use of the mini C-arm fluoroscope. METHODS Four surgeons (3 hand attending surgeons and 1 hand fellow) monitored their radiation exposure for a total of 200 consecutive cases (50 cases per surgeon) requiring mini C-arm fluoroscopy. Each surgeon measured radiation ...

Background and aims: Process industries are known to be hazardous industries. Chemical Industrial process involves several processes such as drilling and production, storage, transportation, and refining. These activities are different in nature. Also, they are different in job Risks. One of the main and dangerous sections of the process is oil reservoir. Therefore, this study aimed to identify...

Introduction: LiF dosimeter has the most application in medicine. This study aimed to evaluate some dosimetric properties of a novel LiF: Mg, Ti. Materials and Methods: An ELEKTA Precise linear accelerator was used to calibrate dosimeters at 6 MV. In this survey, responses of dosimeters were evaluated up to 1000 cGy. Background effect was investigated in two different dosimeter states includin...

The dynamics of bimolecular chemical reactions can be examined in liquid solutions using infrared absorption spectroscopy with picosecond time resolution. On such short time scales, the transient absorption spectra reveal vibrational mode and quantum-state-specific energy disposal, followed by vibrational relaxation as the energy is dissipated to the surrounding solvent. Comparison with energy ...

In this study, the energy dependency for dosimeters of air ionization chambers, lithium fluoride, silicon and plastic scintillator has been studied using the MCNPX Monte Carlo simulation code and simulated for gamma energy in the range of radiotherapy energy. The simulation results show that the response of each of the dosimeters for gamma photon beams in the energy range of 0.2 to 20 MeV varie...
