Abstract AlN is a wide band gap material with promising properties for dosimetric applications, especially in UV dosimetry. In the present research, thermoluminescence method used order to better understand sunlight and X-ray irradiation effects on yttria doped ceramics. general, TL response characterised by broad peak maxima around 400–450 K emission spectrum (400 nm), Blue (480 nm) Red (600 b...

The verification and validation (V&V) of the Serpent 2 Monte Carlo code for 3-D reactor dosimetry applications is being carried out at VTT. Two code-to-code computational benchmark cases were calculated by MCNP 2. efficiency different variance reduction techniques was appraised. part currently includes two experimental benchmarks from SINBAD database: Pool Critical Assembly-Pressure Vessel ...

We describe devices designed for magnetic field exposures in which field amplitude and gradients are controlled simultaneously. Dosimetry based on field continuation of high resolution magnetic field scans and numerical models is compared with validation measurements. The dosimetry variables we consider are based on the assumption that the biological or chemical system under study has field tra...

In the present paper, we report the indigenous development of a neutron-sensitive thermoluminescent dosemeter (TLD) based on CaSO4:Dy Teflon TL disc. The study includes indigenous development of a neutron dosemeter and its response in terms of operational quantity to different energies of neutrons under various irradiation conditions. It was found that the thermal neutron sensitivity of the CaS...

UNLABELLED A comprehensive, SPECT-based, patient-specific 3-dimensional (3D) dosimetry analysis has been performed using 3D-ID, a previously developed software package. The role of the total-body tumor burden, individual lesion size, tumor absorbed dose, and the spatial distribution of the absorbed dose on response and on the time course of tumor shrinkage has been examined in patients with lym...

The unique radiation exposure conditions that exist in computed tomography (CT), during which thin slices of the patient are irradiated by a narrow, fan-shaped beam of x rays emitted from the x-ray tube during its rotation around the patient, have required the use of special dosimetry techniques to characterize the radiation doses to patients and to monitor CT system performance. This section d...

The possibility of using Brazilian stones in gamma high-dose dosimetry was investigated at IPEN using the optically stimulated luminescence (OSL) technique. Agate samples were studied in relation to their OSL dosimetric properties, in this work. The samples were irradiated at a Gamma-Cell system (Co). The calibration curves show a sublinear behavior between 50 Gy and 300 kGy, and the lower dete...

Dosimetry is the science of measuring radiation dosage. The absorbed dose of radiation is measured in a unit called “gray” (Gy). Radiation dosage measurements and ensuring they are as accurate as possible are important if the benefits of the application of nuclear technology in health care are to be harnessed. Radioactive processes and radiation are utilized in many health related technologies,...
