Investigations Chernobyl accident

The study was performed in patients exposed to ionizing radiation after Chernobyl accident. Comparison groups included patients and healthy individuals exposed to the natural radiation levels. Control group included healthy volunteers who resided in Kyiv since Chernobyl accident Distribution by diagnosis is presented at table 1. Investigated persons were at the age of 43-72 (mean+SD for the exposed group 52,3 + 10,1 yrs for control group- 46,3 + 11,3 yrs). All studied persons participated by informed consent. Peripheral blood and bone marrow samples were obtained by a standard procedure (National. Committee for Clinical Laboratory Standards, 1991). Flow... 

Studies of pollutants include the investigation of pollutant movements in water, soil, and the atmosphere. The tracer may be of natural or artificial origin. A widely studied large-scale case is the Chernobyl accident of 1986. 

The activity ratio Pu/ Pu varies depending on source term such as weapon plutonium, fallout from nuclear tests, the Chernobyl accident and releases from nuclear fuel reprocessing plants. The objective of this project was to investigate if there was any close fallout over Madagascar even if it was claimed that all Pu was evaporated in the upper atmosphere. 

In 1986 a iodization of salt started again with the theoretical concentration of 20 mg Kl/kg. During the investigations done in connection with the Chernobyl accident in different parts of Poland it... 

During this human error era thorough investigations of a series of dramatic accidents (Bhopal, Chernobyl, Herald of Free Enterprise), shifted attention more towards the events prior to the accidents and led to the conclusion that the causes concerned more than only technical and human factors. Turner (Turner, 1978), was one of the first to look beyond technical and human factors and concentrated on the sociological and... 

Investigations of industrial accidents reveal that most are caused by human error. The twentieth century s worst industrial disasters—Bhopal, Three Mile Island, and Chernobyl—helped clarify the complex chain of system problems that lead to human error. System problems are problems caused by a process system with built in design and operating deficiencies. The accidents provided numerous checklists and case studies for control room and equipment design. A partial list of some of the problems found at the industrial sites mentioned above are ... 

Chernobyl s 1000 MW Reactor No. 4 exploded, releasing radioactivity over much of Europe. Although much debated since the accident, a Soviet investigation team admitted deliberate, systematic and numerous violations of safety procedures. 

Although relevant exercises have been conducted, and Cold War nuclear weapons programs provide validated analytic platforms, there have been no actual post-det terrorist incidents involving an IND or RDD to date. Consequently, no technical investigations in the contemporary embodiment of nuclear forensic analysis exist for an actual post-det situation, and all discussed case studies necessarily focus on interdicted, pre-det materials. (However, a nuclear accident that is perhaps exemplary of maximum-credible consequences of successful terrorist activities was the uncontrolled criticality and resultant explosion of the Soviet RBMK power reactor at Chernobyl in 1986.)... 

According to industrial accident s investigation 60 to 90% of all accidents have directly been caused by human errors (Brazier et al. 2000). Increasing interest in this area has arisen partly from occurrence of a number of major accidents such as Flixbrough (1974), Seveso (1976), Tree Mile Island (1974), Bhopal (1984), Chernobyl (1986) and many other accidents where human error has played a significant role. 

A well-known accident which demonstrates the meaning of SACs is the Chernobyl disaster in 1986. This accident and the consequences of violating safety rules (SACs) for end users have been analyzed in detail in [3]. In this context psychological factors for violating safety rules are in focus and have been investigated in detail.
