Examining the Relationships Between the Activities of 3H in Precipitation and 137Cs in Ground-Level Air in Belgrade City Area

Assessment of natural radioactivity levels and radon exhalation rate potential from various building materials

“…Re sults ob tained in pres ent in ves ti ga tion are com pa ra ble with data avail able in the lit er a ture [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], Mea sured spe cific ac tiv i ties showed that con struc tion ma te ri als that have been used in Ser bia are in the range given in da ta base for EU coun tries [14]. Fur ther more, the ob tained mean val ues are close to the re ported lower limit for the same type of con struc tion ma te rial.…”

“…There fore, it is im por tant to mea sure the con cen tra tion of radionuclides in all build ing ma te ri als col lected from dif fer ent places and to es ti mate the ra dio log i cal hazards to hu man health. Dur ing the last de cades, there has been an in creas ing in ter est in the study of ra dio activ ity in var i ous build ing ma te ri als [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], and some re sults of mea sured radionuclide con tent in these mate ri als avail able in the lit er a ture are sum ma rized in tab. 1.…”

7Be in atmospheric deposition: determination of seasonal indices

“…Beside monthly average concentration, monthly seasonal index was calculated and this index represents the ratio of the monthly mean value and the overall average value for the examined period [6]. A quarterly seasonal index is the mean of the three monthly indices for the corresponding season, i.e., December, January, and February for winter, March, April, and May for spring, June, July, and August for summer, and September, October, and November for autumn [6]. For determination of linear correlation coefficient between the 7 Be activity and the monthly precipitation amount, database about precipitation from Vinca Institute Radiation and Environmental Protection Department was used.…”
