The Swedish Antarctic Research Expedition named “SWEDARP” was performed during October 1988 through April 1989. The aim of our project was to study the radioactivity in air and water from Gothenburg to the Antarctic. Between Gothenburg and the Equator, the average activity concentration of 7Be in air was 4.3 ± 0.7 mBq/m3. The activity concentration of 7Be in the South Atlantic down to Antarctica varied between 1.3 and 1.7 with an average of 1.5 ± 0.8 mBq/m3. The average activity concentration of 210Pb in air during autumn 1988 on the route Gothenburg- Montevideo was about 290±270 micro-Bq/m3 and on the return in spring 1989 it was about 230±140 micro-Bq/m3. At the Equator, the average activity concentration of 210Pb in November 1988 was about 630±170 and in April 1989 about 260±210 microBq/m3. In the South Atlantic down to Antarctica during February-March 1989, the activity concentration of 210Pb varied between 11 and 58 micro-Bq/m3. The average activity concentration of 210Po in air during the route Gothenburg- Montevideo in 1988 was about 63±58, and on the return, it was about 60±44 The Swedish Antarctic Research Expedition named “SWEDARP” was performed during October 1988 through April 1989.
