Summary

By comparing the natural activities in biosphere and building materials at Chandigarh and Tokyo, we found that at both these places, contamination due to nuclear bomb explosions and nuclear power plants is absent. However, in earth and building materials, members of the radioactive thorium series and40K are in large quantities at Tokyo compared to Chandigarh. The relative concentration of radioactive uranium is comparable at both these places.

Zusammenfassung

Bei Vergleich der natürlichen Aktivitäten in der Biosphäre und in Baumaterialien in Chandigarh und Tokio konnten wir keinerlei atomare Verseuchung durch Atombombenexplosionen und Atomkraftwerke feststellen. Während die relative Konzentration von radioaktivem Uran an beiden Orten gleich hoch ist, wurden in Tokio vergleichsweise große Mengen von Elementen der radioaktiven Thorium-Zerfallskette und von40K in Boden und Baumaterial gefunden.
