The Miniaturized Detector for Application in Space (MIDAS) is a compact device with dimensions 5 x 1 cm3 which combines position sensitive Si detectors and fast neutrons spectrometer. MIDAS developed purpose to act as linear energy transfer (LET) spectrometer the charged particles measure dose equivalent from both neutrons. It based on fully depleted monolithic active pixel sensors track deposi...

Standard neutron fields are invariably accompanied by a photon component due to the neutron-generating reactions and secondary neutron interactions in the surrounding environment. A set of energy-compensated Geiger-Müller (GM) tubes and electronic personal dosemeters (EPDs) have been used to measure the photon dose rates in a number of standard radionuclide and accelerator-based neutron fields....

Background: In this work investigation of the normoxic PAGAT polymer gel dosimeter such as sensitivity, the R2-dose response with post time and the percentage depth dose (PDD) of PAGAT polymer gel dosimeter have been undertaken. Materials and Methods: Using MRI, the formulation to give the maximum change in the transverse relaxation rate R2 was determined to be 4.5% N,N'-methylenbis- ...

Introduction: GRID therapy is a treatment modality in which a high dose of radiation in a single fraction is given to the tumor. This technique previously was used to treat bulky tumors with orthovoltage beams. Recently, studies have been conducted to suggest that GRID therapy with megavoltage photons can be useful in palliative treatments. On the other hand, there has always ...

BACKGROUND The metered dose inhaler is difficult to use correctly, synchronising actuation with inhalation being the most important problem. A breath actuated pressurised inhaler, designed to help patients with poor inhaler technique, was compared with a conventional metered dose inhaler in terms of aerosol deposition and bronchodilator response. METHODS Radioaerosol deposition and bronchodilat...

We usually perform animal studies to provide scientific data or to explain the mechanisms of traditional Korean medicines (TKM) based on their demonstrated efficacy in clinical application or as mentioned in old TKM literature. Similarly, we focus on toxic and safety aspects of TKM using preclinical models so as to promote them as effective over the counter (OTC) or ethical drugs. Often a presc...
