Application of Gamma-Ray Spectroscopy for Using Neem Trees (Azadirachta indica) as Bio Indicators

Abstract

This study explores the use of neem trees (Azadirachta indica) as natural bioindicators for radioactive contamination using high-resolution gamma-ray spectroscopy. Neem trees, known for their phytoremediation potential, can accumulate trace amounts of radionuclides from different sources of regions. Collection of samples from various regions in and around Himayat sagar, Hyderabad is examined for the presence of naturally occurring radionuclides such as potassium-40 (K-40), uranium-238 (U-238), thorium-232 (Th-232), and anthropogenic isotopes like cesium-137 (Cs-137). Identification of hotspots where neem accumulates hazardous substances., Insight into neem's potential as a bioindicator or phytoremediator of contaminated environments, public health implications for consumption of neem-based products in polluted regions, Data to support environmental policies or agricultural guidelines for medicinal plant harvesting. The results highlight the potential of neem trees in passive environmental monitoring of radiological pollution
