An Integrated Methodology for Assessment and Mapping of Land Degradation Risk in Markazi Province, Iran

Desertification is recognized as a serious environmental threat in Iran because of its climatic-geomorphologicconditions. Desertification and land degradation in arid, semi-arid, and dry sub-humid regions, is a globalenvironmental problem. Accurate assessment of the status and trend of desertification is instrumental in developingglobal strategies to prevent and reverse this problem. The goal o...

Assessment of desertification hazard, risk and development of management plans

About 80 percent of Iran is arid and semi-arid and about 35 percent of this area is susceptible to desertification hazard. Therefore desertification assessment and identification of the most important criteria for the assessment of risk and a basis for development of management plans is essential. This research was conducted in the semi-arid region of Agh-Band in the Golestan province, Iran wit...

Appendix C Risk Assessment Methodology and Results

Methodology issues in risk assessment for radon.

The alpha dose per unit radon daughter exposure in mines and homes is comparable at about 5 mGy/WLM. This means that excess lung cancer risk determined in follow-up studies of miners should be valid to extrapolating to environmental populations. There are several models currently used for risk projection to estimate lung cancer in the U.S. from indoor radon exposure. The accuracy of the estimat...
