A study on surface air Beryllium-7 concentration at radionuclide station in Tanah Rata, Cameron Highlands (MYP42) during southwest monsoon seasons in Malaysia

Abstract

Beryllium-7 (Be-7) is a significant radionuclide, primarily produced through cosmic ray interactions with atmospheric elements. Its study can provide insights into atmospheric processes and transport mechanisms. This research investigates the concentration of Be-7 in surface air at the Radionuclide Station (MYP42) located in Tanah Rata, Cameron Highlands, Malaysia, during the Southwest Monsoon season using data from the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) from 2011 to 2021. Meteorological parameters of the study area, such as wind direction, wind speed, humidity, and precipitation, are considered to understand their influence on radionuclide dispersion and deposition. The results from this study are aimed to contribute to the understanding of atmospheric dynamics in the Cameron Highlands region and may have implications for broader atmospheric and environmental studies. The study results suggest no statistically significant variation in Be-7 concentration during the southwest monsoon season, demonstrating minimal fluctuations within and outside the monsoon period. Such insights are crucial for the region’s scientific research and environmental management.
