A Radioactive Waste Information Management System (RAWINGS) currently in operation mainly manages the inventory and history of the operating waste. The system has the disadvantages of the entered information needing to be transferred manually from the site to the system, information getting incorrectly entered during the process or information going missing.

Managing radioactive waste must be carried out within a strict framework and with a constant requirement to protect human beings and the environment. A safety management of the radioactive material or waste (RAM or RW) unavoidably involves transportation activities by using robust safe and reliable packaging system.

Nuclear decommissioning is a worldwide competitive market. It is also the main source of radioactive waste from the nuclear energy field. In order to reduce the waste volume it is necessary to sort the actual radioactive waste to be disposed of and to separate them from other materials that could be recycled.

Thyroid cancer is the second most common cancer diagnosed during pregnancy after breast cancer. The goal of management is to control malignancy and prevent maternal and fetal complications as a result of maternal hypothyroidism. The role of female sex hormones as an etiologic factor was investigated, with no clear association. Pregnancy can cause an increase in size of a previously existed thyroid nodule through the structural similarity between TSH and BHCG, and the normally expressed estrogen receptors on thyroid gland cells.

Study of nuclear fuel cycle in Vietnam at the aspect of domestic production, the exploitation and process of uranium ore were began. These processes generated large amounts of radioactive waste overtiming. The naturally occurring radioactive material and technologically enhanced radioactive material (NORM/TENORM) waste, which would be large, needs to be managed and disposed reasonably by effective methods.

Another closely-related dynamic is a fundamental shift that is taking place in terms of priority geographic markets. A 2011 global CEO survey by PricewaterhouseCoopers (PWC’s Growth Reimagined) found that the large majority of corporate executives have shifted their primary focus to developing markets. Although doing business in these markets is nothing new, making them the primary target market, where firms plan to invest the majority of their efforts and expect the majority of their future sales, is new and significant.

The state uses two forms to create Records Retention Schedules: the Records Retention Schedule Approval Request, STD Form 72 (pdf); and the Records Retention Schedule, STD Form 73 (pdf). The Form 72 contains signature elements from the agency involved, the Records Manager, the approval authority, and an archival review. The Form 73 is the schedule itself and contains an agency description or mission statement plus the listing of all agency records. Both of these forms are for state agencies but could easily be adapted/modified for use by local government.

During my career, some 35 years, there has been a growing realization that the goal of successful nuclear waste management and the final disposal of long-lived radionuclides can only be attained by a thorough understanding of the behavior of key, technogenic radionuclides in the environment. Within a nuclear reactor, these radionuclides are created by fission, neutron capture and subsequent beta-decay reactions on actinides, mainly 238 U, and by activation nuclear reactions.

About 155,000 cubic meters of waste contaminated with both radioactive isotopes and hazardous chemicals are stored at some 30 DOE sites, and another 450,000 cubic meters are buried. While DOE is making a concerted effort to properly dispose of this waste, the amount translates to a multi-decade effort that will require handling, characterizing, and shipping hundreds of thousands of waste containers at a total cost of billions of dollars. This report describes basic scientific research that can lead to new technologies for performing these tasks more safely and cost effectively....

The Department of Energy's Office of Environmental Management (DOE-EM) is responsible for cleaning up radioactive waste and environmental contamination resulting from five decades of nuclear weapons production and testing. A major focus of this program involves the retrieval, processing, and immobilization of waste into stable, solid waste forms for disposal. This report, which was requested by DOE-EM, examines requirements for waste form technology and performance in the cleanup program.

Tritium, the heaviest and only radioactive isotope of hydrogen, is increasing in importance in energy and environmental considerations. This nuclide is widely distributed throughout man's environment because of its ubiquitous form as tritiated water and its persistence in the environment. This report considers and evaluates the available information on tritium in terms of its physical properties, production sources, physical transport, biological behavior, projected future production, waste management, and the long-term dose implications of tritium in the environment....
