Introduction: The most common cancer in women worldwide is breast and radiotherapy the best treatment choice after mastectomy.1,2 In radiation therapy mastectomy, depending on type of tumor, area removed goes under radiotherapy. Methods: TLD (Thermoluminescence Dosimetry) chips were used this project. Typically, each patient an irradiation 200 cGy during 25 sessions received a total 5000 cGy. R...

This report documents how we improved the TLD framework for real-time object tracking [1] by using a new set of features and modifying the learning algorithm.

Proton therapy represents a technologically advanced method for delivery of radiation treatments to tumors. The determination the biological effectiveness is one objectives MoVe IT (Modeling and Verification Ion Beam Treatment Planning) project National Institute Nuclear Physics (INFN) CSN5. aim present work, which part project, was evaluate performance thermoluminescent dosimeters (TLDs-100) d...

One of structural passive control methods is to use Tuned Liquid Damper (TLD). However, because of the nature of the TLD, only one tuning frequency can be created when the water is sloshing. To fix this problem, some installed rotatable baffles can be embedded inside TLD called Variably Baffled TLD (VBTLD) where by changing the angle of the baffles a tuning frequency range is created. This gives ...

Increased HIV drug resistance (HIVDR) with antiretroviral therapy (ART) rollout may jeopardize therapeutic options, especially in this era of transition to fixed-dose tenofovir-lamivudine-dolutegravir (TLD). We studied acquired HIVDR (ADR) patterns and describe potentially active drugs after first- second-line failure resource-limited settings (RLS) like Cameroon. A laboratory-based study 759 p...

This paper describes preliminary work to develop a cosmic-radiation dosemeter for use by military aircraft crew. The dosemeter is based on a combination of CR-39 etched-track detectors and TLD-700 thermoluminescent detectors. It is intended that the CR-39 be used to assess the neutron dose, while the TLD700 is used to assess the photon and charged particle dose. The sensitivity of CR-39 to the ...

BACKGROUND A novel radioactive 125I seed-loaded biliary stent has been used for patients with malignant biliary obstruction. However, the dosimetric characteristics of the stents remain unclear. Therefore, we aimed to describe the dosimetry of the stents of different lengths - with different number as well as activities of 125I seeds. METHODS The radiation dosimetry of three representative ra...

In this study, a new simple model based on the classical treatment of lattice vibrations and the Franck-Condon principle is developed to describe the shape of thermoluminescence (TL) emission bands of crystalline solids. According to developed model, shape of the emission band has a Gaussian form and depends on just two physical parameters: peak energy E0 and broadening of emission spectra U. I...

OBJECTIVE The aim of this work was to determine the radiation dose received by infants from radiographic exposure and the contribution from scatter radiation due to radiographic exposure of other infants in the same room. MATERIALS AND METHODS We retrospectively evaluated the entrance skin doses (ESDs) and effective doses of 23 infants with a gestational age as low as 28 weeks. ESDs were dete...

The aims of this study were to characterize reinforced metal-oxide-semiconductor field-effect transistor (MOSFET) dosimeters to assess the measurement uncertainty, single exposure low-dose limit with acceptable accuracy, and the number of exposures required to attain the corresponding limit of the thermoluminescent dosimeters (TLD). The second aim was to characterize MOSFET dosimeter sensitivit...
