Nuclear medicine would be greatly aided if compounds were available to promote the excretion of unwanted radioisotopes from biological systems. Such preparations would make possible greater use of long-lived radionuclides in medicine and would reduce some of the environmental hazards associated with nuclear energy. The biochemistry of radioisotope excretion is complicated because there are so m...

This article addresses the development of a remotely piloted vehicle for chemical, biological, radiological, and nuclear army defense system, able itself to perform radiometric surveys favoring process local mapping investigation possible dispersions radioactive materials in radiological accidents incidents. Tests were carried out verify efficiency developed prototype it can be verified that ha...

The eleven nuclear power plants in operation, under construction and a well-planned plant in the east coast of China generally use seawater for reactor cooling. In this study, an oceanic dispersion assessment system based on a database of tidal harmonic constants is developed. This system can calculate the tidal current without a large computational cost, and it is possible to calculate real-ti...

Uranium aerosols are released from uranium-containing materials in high-temperature environments caused by nuclear accidents or other processes. Research on the generation characteristics of uranium under such conditions is an important part nuclear-safety analysis. In this experiment, similarity between metal cerium and material was evaluated aspects particle size distribution source term. Com...

Nuclear energy has significantly promoted the development of human society. However, nuclear pollution caused by accidents can lead to significant hazards environment and health. As a major radioactive product, iodine (mainly existing as I−) detection attracted attentions. In this study, zirconium(IV) is used enhance oxidation environmental I− form I2. Subsequently, generated I2 oxidizes chemic...

Two serious nuclear accidents during the last quarter century (Chernobyl, 1986 and Fukushima, 2011) contaminated large agricultural areas with radioactivity. The database "Seeds in Chernobyl" (http://www.chernobylproteomics.sav.sk) contains the information about the abundances of hundreds of proteins from on-going investigation of mature and developing seed harvested from plants grown in radioa...

In keeping with the traditional emphasis on safety, nuclear technologists were prompted by the Chernobyl accident (1986), to consider the consequences of accidents Beyond the Design Basis Accident (BDBA) scenarios, despite the fact, that the probability of such an occurrence was considered extremely low. These consequences, though highly unlikely, necessitate additional measures to protect the ...

The recent loss of lives and traffic jams (Figure 1) for tens of miles as hurricanes Rita and Katrina approached the Gulf coast demonstrate the enormous difficulty in evacuating urban areas [6]. Besides hurricanes, evacuation may be necessary due to other potential disasters, e.g., fire, terrorism, and nuclear or chemical plant accidents. Thus, the local emergency management community engages i...

LITTLE ATTENTION HAS BEEN GIVEN TO SLEEPY NEARMISS DRIVING ACCIDENTS UP TO NOW DESPITE THEIR LIKELY RELATIONSHIP WITH ACTUAL DRIVING accidents. Although there have been investigations that included near-miss accidents and/or sleepy near-misses, these data were limited and not used to predict a sleepy accident.1-5 In fact, the focus of these and the following papers were mostly on sleep disorder...
