An integrated Laser Ablation Fluid RAdiation simulation Code (LAFRAC) has been developed to estimate behaviors of highly energetic ions and neutral particles from laser produced plasmas, and to estimate ionization and recombination processes. Neutral particles cannot be controlled by electric and/or magnetic forces. Therefore, estimation of the number of neutral particles and mitigation of them...

This paper describes results of the radiation environmental monitoring performed in the Chernobyl Exclusion Zone (ChEZ) during the period following the 1986 Chernobyl Nuclear Power Plant accident. This article presents a brief overview of five comprehensive reports generated under Contract No. DE-AC09-96SR18500 (Washington Savannah River Company LLC, Subcontract No. AC55559N, SOW No. ON8778) an...

Although well described in the 1960s, liver toxicity secondary to radiation therapy, commonly known as radiation-induced liver disease (RILD), remains a major challenge. RILD encompasses two distinct clinical entities, a 'classic' form, composed of anicteric hepatomegaly, ascites and elevated alkaline phosphatase; and a 'non-classic' form, with liver transaminases elevated to more than five tim...

[1] The Moon spends 25% of its orbit within the terrestrial magnetosphere. The magnetic field from the terrestrial magnetosphere can potentially provide radiation shielding from solar energetic particle events and lower energy galactic cosmic rays, which can be a significant hazard during extra-vehicle activities or during human exploration of the lunar surface. The level of shielding provided ...

An improvement to an existing technique for the reduction of emissions from PLC networks is proposed. Using numerical simulations, the technique is shown to reduce anyone of the components of the radiated magnetic field by up to 80 dB for a theoretical case. The applicability of the technique to real networks is discussed. INTRODUCTION Electromagnetic radiation from PLC signals may cause interf...

Despite the antenna’s privileged position as the first line of defense against interferers, jammers and spoofers, most detection and mitigation techniques are realized in the receiver’s backend signal processing blocks. Nonetheless, these solutions often require considerable additional hardware added to the receiver’s frontend and antenna design. For example, multi-antenna arrays replace a sing...
