In this book I provide a solution to nuclear reactor core meltdown. That will save lives and the enviroment (this could have helped at Fukushima, Japan). The radiation fallout effects are detailed since 1945, along with basic nuclear reactor anatomy, and a breif explanation of "fission," so anyone can understand how nuclear power is developed and used. How the "radiation" is introduced into our food chain is illustrated. In addition to this a list of some nuclear 'accidents' from around the world along with incredible as it might sound "lost nuclear weapons " To top it all off a glossary of terms. This book will literally blow you away

Master's Thesis from the year 2013 in the subject Physics - Quantum Physics, grade: -, Shahjalal University of Science and Technology (Department of Physics), course: Nanostructure Physics, language: English, abstract: We have numerically investigated parametric variations of transmission peaks of symmetric rectangular double barrier in non-tunneling regime. We have compared the variations with those for tunneling regime. One of the three variations in non-tunneling regime is completely different from that for tunneling regime warranting rapid dissemination. The book contains background on Quantum Mechanics, Microelectronics and Nanostructure Physics to enable readers assimilate the book completely.

The study of the nucleon-nucleon interaction has a long history, going back to 1932 (just after the discovery of the neutron by James Chadwick). The force is responsible for binding protons and neutrons into atomic nuclei but, unlike the cases of Coulomb or Newtonian gravitational laws, the form of the fundamental NN strong interaction and its constants are a priori unknown. The subject is nevertheless important because the energy associated with the binding of protons and neutrons to form atomic nuclei is the energy used in nuclear power. The authors of the present volume deliver accounts of current research on various aspects of the forces between two or more nucleons and how they relate to experiments in nuclear physics. General overviews, illustrated by appropriate examples, are given both the theoretical and experimental knowledge of nuclear physics that are prerequisites for the understanding of the strong interaction. Two- and three-nucleon forces are among the topics that are addressed and discussed including, for example, how nuclear forces emerge from low-energy QCD via chiral effective field theory. A comprehensive overview is presented of realistic free nucleon-nucleon interactions and also two-nucleon dynamics in a nuclear medium.

Master's Thesis from the year 2011 in the subject Physics - Quantum Physics, grade: -, Shahjalal University of Science and Technology (Department of Physics), course: Nanostructure Physics, language: English, abstract: This book contains a comprehensive account of application of WKB method to pure Physics of nanostructures containing single or symmetric double barrier V(x) in their band model in presence of longitudinal magnetic field applied along x direction. It concentrates on effects on transmission coefficient of single and symmetric double barriers by three dimensional electron gas (3DEG). Analytical expressions for longitudinal magnetic field dependent transmission coefficient of single and symmetric double barrier of general shape are obtained first. These general expressions are then used to obtain analytical expressions of longitudinal magnetic field dependent transmission coefficient of single and symmetric double barriers of many different shapes we encounter in studying nanostructure Physics. This is followed by thorough numerical investigation to bring out effects of longitudinal magnetic field on transmission coefficient of all these barriers. Comparisons with standard results where available showed excellent agreements. Results of numerical investigation have been explained completely. The book makes well documented, with thorough calculation and discussion, pure Physics of semiconductor nanostructures.

In April of 2012 the Plutonium Sustainment program at LANL completed or addressed the following high-level activities: 1) Construction activities on the Low Voltage Electron Beam (LVEB) Welder and Analytical Chemistry gloveboxes have started, successfully closing out MRT L2 Milestone 4195; 2) Completed installation of the Surface Preparation unit in PF4. The unit will be functionally tested in May; 3) Completed casting of the first two near net shape W87 hemishells; 4) Delivered Revision 3 of the Plutonium Sustainment and Manufacturing Study; 5) Completed machining and inspecting the first set of Pollux parts on Precitech 1; 6) Attended the Pu Sustainment Second Quarter Mid-Year Review and the Pit Production Integrated Project Team meeting in Livermore, providing technical updates across the Plutonium Sustainment portfolio; 7) Analyzed the program impact of the LANL Voluntary Separation Program. The analysis determined an impact of 24.6 FTEs and a budget impact of approximately $3.2 Million Dollars of pull back; 8) The Power Supply Assembly Area project received a LANL Pollution Prevention "Gold" award in the category of Cradle-to-Cradle - Cleanouts. A gold award is presented to the number one project in its pollution prevention category. There are currently no major issues associated with achieving MRT L2 Milestones 4195-4198 or the relevant PBIs associated with Plutonium Sustainment. There are no budget issues associated with FY12 final budget guidance. Table 1 identifies all Baseline Change Requests (BCRs) that were initiated, in process, or completed during the month. The earned value metrics overall for LANL are within acceptable thresholds, so no high-level recovery plan is required.

This book dispels popular myths and misconceptions about the dangers of radiation and puts radiation exposures in perspective by showing how much radiation we receive from nature without harm. It also discusses the theories of radiation effects on health and the risks from various sources such as plutonium and the Fukushima reactor leaks.

This work is a study of scintillator-based radiation detectors, and how they perform using both traditional and modern photodetectors. More specifically, we examine how a radiation detector utilizing silicon photomultiplier-based readout performs compared to a traditional photomultiplier tube-based detector. Silicon photomultipliers show great promise in contemporary particle physics for their small size, robustness, and efficiency compared to traditional photodetector systems. We investigated the practicality and efficiency of using silicon photomultipliers in radiation detectors.

This book presents one of the latest measurements (2012 May) of the neutrino velocity performed with the OPERA detector in the CNGS beam. This analysis is different from the previous ones for two main factors. From the CERN side, it uses a dedicated bunched beam instead of the standard high intensity OPERA beam, which allows a better time distribution of the events; while at the LNGS the analysis has been performed using a a dedicated time measurement based on the RPC sub-detector, which is partially independent from the standard OPERA timing system. The obtained result is the one with the smallest statistical uncertainty with respect to the other LNGS experiments and to the OPERA standard analysis. The book starts with an introduction to neutrino physiscs and OPERA experiment. Then, all the measurement details will be explained in order to end up, in the fifth chapter, to the data analysis. As in all the other LNGS experiments, the results consists in the measurement the neutrino Time of Flight with respect to the light Time of Flight. Using the CNGS spectrum the result is then expressed in term of a mass limit on the neutrino.

In this work are used two types of detectors scintillation NaI(Tl) sizes (2"x2"), (1"x1.5")for a comparative study between them and are used two sources of radioactive cobalt Co-60 has two energy (1.33&1.73 MeV), cesium has energy (0.662 MeV) . and calculating the total area of the spectrum space scattering and area of peak optical and portability energy analysis, found the size large for crystal detector leads to probability escape photons outside the crystals to be less because it can reveal again and recorded pulse with pulse recorded by the electron apostate so increase the value of portability energy analysis, and increase the volume of detectors cause increased probability for scattering Compton, In other words the increase in the probability of interaction effect photoelectric be less than the increase in the probability of interaction scattering Compton so the Net Area under the peak at less an increase of scattering spectrum
