Physics is the science that studies the interaction between matter and energy. This discipline studies the general properties of bodies, the forces that modify the transfer of energy and the interaction between particles. Physics now has many branches, and one of them is the Biomedical Physics. Biomedical Physics in Medicine applies the principles and methods of physics. This will generate new ...
RISC-RAD Radiosensitivity of Individuals and Susceptibility to Cancer induced by Ionizing Radiations
LEO orbit space radiations in which the protons has the main contribution, have survived devastating effects on electronic components. The damage caused by ionizing protons on the satellite electrical components in the circuit LEO moves was reviewed. By studying the LEO orbit by Shieldose software, the worst-case scenario was evaluated for a satellite. Considering the electronic components base...
The ionizing radiations are able to make either a permanent or temporarily damage in the electronic circuits. The temporary effects during irradiation can be used to detect the ionizing radiation. In this study a diode in reverse bias has been used to investigate the effects of ionization radiation on semiconductors. The variation of reverse current of diode has been monitored due to interactio...
In this study, the detection of alpha particles in the high current mode is investigated in the presence of two gaseous electron multipliers in the micro-pattern structures. Thick Gas Electron Multiplier (TGEM) and an Electron Multiplier Assemblies (EMA) were designed and constructed as amplification gap in the detector chamber. An ion chamber is employed to measure the current of interaction b...
In vitro grown callus cultures of Ipomoea batatas were exposed to flame treatment and electromagnetic radiations generated by mobile phone. The cultured tissues responded the treatments as evidenced significant reduction phenolic contents compared controls. Even though growth was normal, there a change in content tissues. There exhibited not much variation among regarding rate. morphology textu...
