“…The annual effective dose rate received by the local residents outdoor due to natural radioactivity in soil ranges from 0.05 to 15.6 mSv yr-1 with an average of 2.2 mSv yr -1 . The dose rate was higher than that of the studied thermal power plant and the global average for outdoor exposure [20].…”

Industrial practices involving natural resources often concentrate radionuclides to a degree that may pose a risk to humans and the environment. In the present study, Tchnically Enhanced Naturally Occuring Radioactive Materials TE-NORM are generated from the combustion of natural gas and fuel oil in a typical thermal power plant in Egypt. They were accumulated in the form of sludge or scales inside pipes, separators, heaters, storage tanks, and any other plant equipment or deposited in the soil surface land of the thermal power plant. The average measurements of the radioactivity of radionuclides in the contaminated soil of the thermal power plant were used as input data for the RESRAD computer code to estimate the radiological doses and health risks to the workers. In this assessment, the exposure source parameters were adjusted a period of 100 years. The predicted maximum total effective doses equivalent (TEDE) for the external exposure and soil ingestion of the contaminated area received by workers were 17.4and 0.106 Sv/y, also their annual total cancer risk for the external exposure and soil ingestion were 2.9 x10 -5 and 2.68 x 10 -8 respectively. It is found that the estimated doses and risks received by workers were below the international limits.

“…In previous research it was detemined that activity concentration of radionuclides in the mosses coud be used as effective indicator of radioactivity pollution in different polluted zones (El-Gamal et al, 2013;Minkina et al, 2014). In research El-Gamal et al (2013) it was shown that mosses are used for urboecomonitoring for definition of high radioactivity levels around assiut thermal power plants. In investigation of Minkina et al (2014) describes additional influence of of heavy metal attendant anion on adsorbtion of polluted material by plants system.…”

Contamination of environment by radionuclides in territories under urboecosystem conditions is actual problem. The search of new express methods for radioactivity determination of environment is important task of research. In present work it was shown that mosses are bioindicators of radioactive contamination, because they accumulate radioactive substances in high concentrations. Using of bryoindication methods are promising techniques for the assessment of the contamination of ecosystems with radionuclides. The use of epiphytic mosses is the most efficient technique for assessing the contents of radionuclides in the surface air layer. The epiphytic moss (Pylaisia polyantha) growing in different zones of the city of Rostov-on-Don, was used for the radioactivity biomonitoring of urbosystems. The accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. It was shown that Pylaisia polyantha is effective indicator of radioactivity for biomonitoring. The activity concentration of 137 Cs, 226 Ra, 40 K and 232 Th in the samples of moss, soils and aerosol air have been compared. The capacity of Pylaisia polyantha to accumulate radionuclides has been estimated for four radionuclides (137 Cs, 226 Ra, 232 Th and 40 K) with consideration for the background level. On the basis of radionuclide analysis, zones in the city of Rostov-on-Don with the highest accumulation coefficients of 137 Cs, 226 Ra, 40 K and 232 Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones. The results of investigation showed that the epiphytic moss (Pylaisia polyantha) can be used as indicator of radioactivity pollution in different polluted zones.
