Measuring the radioactivity concentration of 40K and 137Cs and calculating the annual internal doses from ingesting liquid and powdered milk

The assessment of the annual effective dose due to ingestion of radionuclides from drinking water consumption: calculation methods

“…The assessment of the effective dose due to water and food consumption in the world population varies according to geographic specificity, seasonal cultural and food habits, in the range 0.2-0.8 mSv year −1 [1]. There are many studies to assess the annual effective dose due to ingestion of radionuclides by food consumption [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], and by water consumption , which use different calculation methods of this physical magnitude.…”

Measurement of Radioactivity in Carbonated Soft Drinks and Annual Dose Assessment

“…232 Th and 238 U and their associated progeny (such as 214 Pb, 212 Pb, 214 Bi, 228 Ac, …) as well as 40 K are usually the most found natural radionuclides in earth samples. Some artificial radionuclides, such as 134 Cs, 137 Cs, 90 Sr and 131 I [1] [2] could be present with a small activity in food, water or beverages (juices, soft drinks). These artificial radionuclides are a consequence of human nuclear activities.…”
