Article Synopsis
- The review analyzed research articles focusing on radioactivity and dose estimates from the Bahi district and other areas in Tanzania, highlighting variations in gamma ray dose rates among researchers.
- The reported radioactivity concentrations in soil varied for radium (Ra), thorium (Th), and potassium (K), showing a range from 28.5-57.4 Bq/kg for Ra, 38.1-521.3 Bq/kg for Th, and 562.9-665.0 Bq/kg for K.
- Additionally, worries were noted regarding water well and swamp samples, although uranium levels in cereals remained within acceptable limits, emphasizing the need for further studies to develop a better understanding of baseline data.
Characterisation of a novel discolornolide () isolated from a first time investigation of is described. Other 6 known compounds, karatavin (), -acetylanonaine (), quercetin-3--arabinose (), stigmasterol (, a mixture of stigmasterol and β-sitosterol () and octahydro-5-isopropyl-3-methyl-2-methyleneazulene-8,8-diol () isolated are also reported. The structures were established by spectroscopic methods.
