Introduction Application of near-infrared absorbing nanostructures can induce hyperthermia, in addition to providing more efficient  photothermal effects. Gold-gold sulfide (GGS) is considered as one of these nanostructures. This study was performed on a tissue-equivalent optical-thermal phantom to determine the temperature profile in the presence and absence of GGS and millisecond pulses of a ...

Background: In this study, measurement of indoor radon and its progeny levels was carried out in Gas Turbine Power Station in Haryana ( India ), where natural gas is used as fuel. For comparison, the results of a study carried out in thermal power plant in Haryana are also presented. Radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

The Kansai BNCT Medical Center has a cyclotron based epithermal neutron source for clinical Boron Neutron Capture Therapy. system accelerates proton to an energy of 30 MeV which strikes beryllium target producing fast neutrons are moderated down use. While studies in the past have shown be highly effective malignant melanoma skin, apply superficial lesions using this it is necessary shift therm...

Background: Tea is one of the most popular beverages all over the world which is prepared from the leaves of a shrub camellia sinensis. Eastern Black Sea Region of Turkey which account for around 100% of all tea production in Turkey was among the areas contaminated by Chernobyl accident. Materials and Methods: A comprehensive study was planned and carried out to determine the level of ...

Neutrons constitute a major component in the radiation fi eld outside the shielding of particle accelerators. Consequently appropriate neutron dose meters are needed to survey the radiation levels. A thermo-luminescence based neutron dosemeter is used at the UNILAC as well as at the SIS. It has been modifi ed to improve the response for high energetic neutrons (extended range). We report on a t...

The HANARO neutron irradiation facility for various applications in the boron neutron capture therapy (BNCT) field was developed, and its characteristics were investigated. In order to obtain the sufficient thermal neutron flux with a low level of contamination by fast neutrons and gamma rays, a radiation filtering method was adopted. The radiation filter was designed by using a silicon single ...

Background: High-energy linear accelerator (linac) is a valuable tool and the most commonly device for external beam radiation treatments in cancer patients. In the linac head, high-energy photons with energies above the threshold of interaction produce photoneutrons. These photoneutrons deliver the extra dose to the patients in the planning treatment and increase the risk of secondary cancer.O...
