- The study measured the levels of radionuclides (Ra, Th, K, Cs) in soil and tea leaves from the Udalia Tea Estate in Chittagong, Bangladesh, using high purity germanium γ-ray spectrometry.
- Average concentrations of these radionuclides were lower in tea leaves compared to the soil, and the transfer factors indicated a relatively low uptake of radionuclides from soil to tea.
- The estimated radiation dose from drinking tea was considered low and below the UNSCEAR reference limit, suggesting minimal health risks, but ongoing monitoring of radiation levels in tea is recommended to ensure safety.
