The paper deals with the presentation of modern quantitative methods for assessing environmental risks. It evaluates individual methods in terms of their suitability for use in individual phases of the risk assessment process. The qualitative comparison of individual methods and techniques is based on predefined criteria. A multi-criteria decision-making method was used for the comparison of the methods and techniques. Methods of Fault tree analysis, Event tree analysis, Monte Carlo simulation, RM/RA CRAMM methods...

All nuclear power plants in Slovakia can effectively prevent emergencies caused by technical or human error. Before commissioning, they must demonstrate to the Nuclear Supervisory Authority that the plant can respond to even extremely unlikely events. The design of the plant has safety systems that will prevent damage to nuclear fuel and the release of radioactive substances so as not to endanger human health and the environment. The maximum design accident for a WWER-440 reactor is a rupture of the main circulati...

Radioactive radiation is the common part of our lives due to natural sources producing the radioactive radiation. The radiation coming from the nuclear power plants is very law comparing to natural or common sources unless some accident happens. The paper deals with two well-known major nuclear power plant incidents and one local silent accident which took place in Czechoslovakia. Three Miles Island as an accident with no direct fatalities is introduced from the medical consequences point of view. Some longterm re...

The tornado phenomenon is getting to more attention in recent years due its unexpectedoccurrence in the areas where it was traditionally extremely rare. The European strongesttornado since 2001 appeared in Southern Morava region, Czech Republic, June 24th 2021.The paper deals with the incidence of tornadoes, the ways of prediction and measurementas well as the protection advices. The believed life cycle and possibilities of themonitoring, forecasting with the current satellite system as well as their limits werein...

The paper deals with quantitative methods of risk management applied to a crisis event of criminal origin. Two quantitative risk assessment methods are introduced. The event tree analysis and the RM/RA CRAMM method are applied from the perspective of crisis management in the phase of criminal crisis prevention. The advantages and disadvantages of the quantitative methods compared to qualitative methods are discussed. The quality of input data is accented to get reliable results that can be seriously taken into acc...

The paper deals with the quantitative risk assessment approach to the use of the universal quantitative method RM/RA CRAMM. The method is applied to criminality cases related to arson and other cases of environmental insensitivity influenced by social background. The arson statistics recorded in Slovakia are usually hidden behind other reasons of the fire cause. The hypothesis is that there is a certain impact of the social environment on criminality, including arson behaviour. The quantitative method needs quanti...
