Soil is the foundation of the entire biosphere, and the most important complex interface for the global transformation and interchange of matter and energy. Also, only a healthy, that is, biologically active soil warrants the sufficient production of food for the growing human population.

The results of the three independent experiments on study of molecular and cellular effects in CBA/lac male mice chronically (up to 1 year) exposed to γ-radiation at a dose rate of 61 cGy/year are reviewed in this chapter. It was shown that the DNA–protein cross-links level was statistically increased only at early terms of irradiation (up to 40 days (~6.8 cGy) ).

This chapter contains the assumption about a novel perspective on the relationship between foreign direct investment (FDI) and the stringency of environmental policies. We have created, by means of powerful econometric apparatus, possible models for equality of positive and negative influences of FDI on environmental security.

This chapter reviews the past and present national and international mitigation programs, their respective major areas of activities, financing, and implementation, as well as adequacy and efficiency of the strategies used in addressing the problems that followed the Chernobyl catastrophe 26 April 1986.

This paper gives an overview of some of the main sources of uncertainty in Ecological Risk Assessment (ERA). These include numerical or statistical uncertainties (equivalent to ), model and scenario uncertainties (), epistemological uncertainties ( or ) and ethical-social uncertainties. The paper argues that scientists and policy makers need to appreciate the deeper dimensions of uncertainty, and to go beyond a simple, numerical evaluation of uncertainty. Many of the challenges that multiple stressors raise for risk assessors reflect the fact that the uncertainties associated with multiple stressors are difficult to quantify and irreducible. The focus should be on a better understanding of the basic biological processes and mechanisms by which stressors interact.

Preventive policies for areas potentially exposed to radioactive contamination require management decisions which weigh the benefits of prevention against the risks and disruptions associated with their implementation. A framework is needed that integrates risk assessment and engineering options, compares options for risk reduction, communicates uncertainty, and effectively allows reiteration of the decision-making process. In the first part of the chapter, a brief description of 1986 Chernobyl accident and its Romania’s related experience is done.

The purpose of this chapter is to examine the difficulties associated with legislating in areas where there is incomplete or no knowledge.
