In the frame of the accountancy measurements of the fissile materials, reliable determinations of the plutonium and uranium content in spent nuclear fuel are required to comply with international safeguards agreements. Large-sized dried (LSD) spikes of enriched 235U and 239Pu for isotope dilution mass spectrometry (IDMS) analysis are routinely applied in reprocessing plants for this purpose. A ...

Introduction: In the last 5 years the American Association of Physicists in Medicine Task Group 51 (AAPM TG-51) and the International Atomic Energy Agency (IAEA) published a new high-energy photon and electron dosimetry protocol. These protocols are based on the use of an ion chamber having an absorbed-dose to water calibration factor. These are different from the previous NCS report-2 and IAEA...

Introduction: The accuracy of dose calculation algorithm (DCA) is highly considered in the radiotherapy sequences. This study aims at assessing the accuracy of five dose calculation algorithms in tissue inhomogeneity corrections, based on the International Atomic Energy Agency TEC-DOC 1583. Material and Methods: A heterogeneous phantom was sc...

Nuclear fission energy is considered to be somewhere between the holy grail, required to solve all energy worries of the human industrialized civilization, and a fast path directly to hell. Discussions about future energy sources and the possible contribution from nuclear energy are often dominated by variations of fundamentalists and often irrational approaches. As a result, very little is kno...

The energy sector’s transition from a fossil fuel-based system to an energy-efficient renewable sources is recognized as indisputable and undeniable. However, the primary that comes today only 5% of world consumption. Thus, will require lot time effort in field international policy. First, effective measures should be taken increase use level reduces climate change. prominent active persons who...

The history of the International Atomic Energy Agency (IAEA) and the Nuclear Non-Proliferation Treaty (NPT) demonstrate that peaceful nuclear energy is a myth. As our January 2007 Briefing, “Civil Nuclear Power and Nuclear Weapons Proliferation”, explains promoting ‘peaceful’ nuclear power has accelerated nuclear weapons proliferation. Nuclear reactors in India, Pakistan, Israel, and North Kore...

The Nuclear Science References (NSR) database, and associated Web interface, is the world’s only comprehensive source of easily accessible lowand intermediate-energy nuclear physics bibliographic information for more than 200,000 articles since the beginning of nuclear science. The weekly-updated NSR database provides essential support for nuclear data evaluation, compilation and research activ...
