Radiation Damage of Electronic and Optoelectronic Devices in Space

Secondary Particles Produced by Hadron Therapy

Introduction Use of hadron therapy as an advanced radiotherapy technique is increasing. In this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. In this study, Monte Carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. Materials and Methods I...

اثر تمرین هوازی منظم بر شاخص‌های آسیب اکسیداتیو لیپیدها و پروتئین ها در رت های مواجهه یافته با اشعه ساطع شده از روتر Wi-Fi

Background & Aim: Electronic and communication devices have largely become a part of our daily lives. And this has caused a growing concern with regards to the possible side-effects of exposure to the radiation of these devices on human health. To investigate the same, a research was undergone to study the "Effect of regular aerobic exercise on oxidative damage markers of lipids and protei...

NASA Electronic Parts & Packaging ( NEPP ) Program Assurance Research on Optoelectronics

The wide variety of optoelectronics applications in NASA flight systems and instruments require that optoelectronic technologies meet the demanding requirements of the space environment throughout mission life. These requirements vary widely from intense radiation near Jupiter to the very cold temperatures on the Martian surface to the effects of solar flares in Earth orbit. Considerable work h...

Poor Understanding of Radiation Profiles in Deep Space Causes Inaccurate Findings and Misleading Conclusions

The radiation environment in deep space, where astronauts are behind the shelter provided by the Earth’s magnetosphere, is a major health concern. Galactic cosmic rays (GCR) and solar particle events (SPE) are two basic sources of space radiation in the solar system. The health risks of exposure to high levels of space radiation can be observed either as acute and delayed effects. Zhang et al. ...
