Survey of the impact of enhanced natural radioactivity on human and natural environments: The example based on PORANO project

Abstract

Abstract. Technologically enhanced naturally occurring radioactive materials (TENORM) touch many aspects of our life. Alterations of the natural composition of rocks during mining and processing may results in an increment of radiation risk to not only humans but wild plants and animals. Each particular type of TENORM determines a unique scenario of exposure. The "PORANO" project is focused on three aspects related to this theme:• methods of monitoring of TENORM occurrence, • methods of applying radiation risk assessment, • regulation improvement. All above aspects of are considered -occupational, public and environmental risk. Also, the effect of associated pollutants interaction are taken into account. The mining industry, as a source of contamination for vast land areas, will be subject to major environmental investigations. The well scientifically justified assessment of TENORM impact on workers and the environment is the most important effect of the project. Developed measurement procedures, sampling strategies, risk assessment and mitigation methods will create a base for the improvement of national environmental monitoring. In the future all developed methods will be applied for assessment of natural background at sites for emerging Polish NPP as well as locations in the vicinity of radioactive waste repositories.

Environmental Impact Assessment of Remediation Strategy in an Oil Spill in the Ecuadorian Amazon Region

“…Ionizing radiation for human health and ionizing radiation for ecosystems: the environmental impact would be related to the presence of radioactive waste in the environmental liability, because in the presumed date that the spill at well Sacha 124 occurred, environmental considerations for crude oil production did not meet adequate technical standards. According to [52], crude oil, sludge, formation waters and gas, among others, are a considerable source of TENORM, due to the high content of radionuclides in the rocks that have existed since the formation of the earth, which also accumulates over time [52,[67][68][69]. A predominant factor is its characteristic of being bioaccumulative.…”
