Production of an economic high-density concrete for shielding megavoltage radiotherapy rooms and nuclear reactors
Background: In megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. The use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. In a nuclear reactor, neutron radiation is the most difficult to shield. A method for p...

متن کاملDeveloping a mobile application for usual calculations of radiotherapy physics
Introduction: Successful radiotherapy requires the precise application of a radiation dose to cancerous tissue, which can be achieved by the design of proper treatment methods by radiotherapy physicists. Tasks performed by radiotherapy physicists include verifying the accuracy of dose calculations, correct treatment planning and the proper functioning of accelerators. They are...
متن کاملA Monte Carlo Study for Photoneutron Dose Estimations around the High-Energy Linacs
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...
متن کاملPerformance of High-strength Concrete Made with Recycled Ceramic Aggregates
Recent scientific concerns to achieve sustainability in construction have suggested the implementation of using recycled aggregate in concrete because it has the potential to reduce the demand for extraction of natural raw materials and decrease the volume of wastes landfilled. In this respect, this study aims to investigate the suitability of using ceramic tile (CT) and ceramic sanitary (CS) w...
