The natural radioactivity level of heavy oil, ash and soil samples around Assiut Thermal Power Plant (ATPP) in Egypt was determined using gamma ray spectrometry. The average concentrations of 226 Ra, 232 Th and 40 K in fly ash were found to be 2307±143, 1281±80 and 1218±129 Bq kg −1 , respectively, while the corresponding values in soil samples were 2670±107, 1401±78 and 1495±100 Bq kg −1 , respectively. These are extremely high and higher by several orders of magnitude than the worldwide population-weighted average values in soil. The radium equivalent activity, the air absorbed dose rate, external hazard index and the annual effective dose rate were calculated and compared with the international recommended values. All averages of these parameters are much higher by several orders of magnitude than the international recommended values, indicating significant radiological health hazards around ATPP due to the radionuclides in the soil. Moreover, the water samples investigated have high activity concentrations indicating that the water is highly contaminated with radioactive materials. The results of the current study highlight the severity of this radioactive pollution on the population in the vicinity of ATPP.

Atmospheric particles in the surface air including aerosol and dust were collected using high volume air sampler (HVAS) for obtaining the activity levels of 210 Pb and 210 Po over Malaysian waters during the EPSP'09 Scientific Expedition. The average mass concentration of total suspended particles (TSP) in maritime air was 33 ± 2 µg/m 3 (ranged from 13 ± 1 to 74 ± 4 µg/m 3 ). Based on previous literatures, it has been suspected that the haze episodes were mainly due to forest and peat bog fires as well as vehicle and industrial emissions during dry period, especially during southwest monsoon. Consequently, the activity levels of 210 Pb and 210 Po in maritime particles were relatively in proportion with the TSP concentrations. Meanwhile, the temporal variation of 210 Po/ 210 Pb activity ratios in the aerosol samples perhaps related to the difference of residence time airborne particles and contribution from different sources of radionuclides in which 210 Pb and 210 Po are not in secular equilibrium. The highest TSP concentrations and 210 Pb and 210 Po activities were closely related to warm and dry period during southwest monsoon.

“…A large proportion of the radioactivity is remains in the bottom ash after combustion. About 0.5-2 % of the total ash resulting from the fly ash combustion is released to the atmosphere and this event creates a potential risk for the very close environment of the coal fired power plant [5]. The amount of coal required to produce 1 GWh of electricity per year is 3×10 9 kg.…”

Abstract. Use of the coal in order to generate electricity increases the exposure of people to radiation. In this paper, the activity concentrations of nuclides 226 Ra, 232 Th and 40 K in samples of coal and bottom ash from the Yatagan Coal-Fired thermal power plant determined using gamma ray spectrometer with a NaI(Tl) scintillation detector. The mean activity concentrations of 226 Ra, 232 Th, and 40 K in the coal were found to be 37.2±2.8 Bqkg -1 , 51.8±3.4 Bqkg -1 and 166.7±11.1 Bqkg -1 , respectively. Whereas in the bottom ashes, the concentrations of the corresponding radionuclides were found to be 62.2±5.6 Bqkg -1 , 87.4±5.9 Bqkg -1 and 221.0 ±12.5 Bqkg -1 , respectively. The findings show that bottom ashes show higher activity concentrations of related radionuclide to coal samples. The absorbed gamma dose rate in outdoor air DR OUT and annual effective dose rate (AED) from coal were calculated to define radõologõcal rõsk. The average findings of annual effective doses were detected as 68.6±5.1 µSvy -1 and 110.3±11.2 µSvy -1 , respectively.
