“…Once created, it promptly associates with minuscule particles. The atmospheric presence of Be-7 is uneven, influenced by geographical location, solar activity, the interchange of air masses within the Atmosphere, and its removal efficiency from the troposphere [6]. With an energy of 477.6 keV and a half-life of 53.3 days, which is relatively short [7], it is easily detected and identified using gammaspectrometry with an HPGe detector.…”

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.

Abstract. 7Be and 210Pb air concentration and depositional flux data provide key information on the origins and movements of air masses, as well as atmospheric deposition processes and residence time of aerosols. After their deposition onto the Earth's surface, they are utilized for tracing soil redistribution processes on land, particle dynamics in aquatic systems, and mixing processes in open ocean. Here we present a global dataset of air concentration and depositional flux measurements of atmospheric 7Be and 210Pb made by a large number of global research communities. Data were collected from published papers between 1955 and early 2020. It includes the annual surface air concentration data of 7Be from 367 sites and 210Pb from 270 sites, the annual depositional flux data of 7Be from 279 sites and 210Pb from 602 sites. When available, appropriate metadata have also been summarized, including geographic location, sampling date, methodology, annual precipitation, and references. The dataset is archived at https://doi.org/10.5281/zenodo.4785136 (Zhang et al., 2021) and is freely available for the scientific community. The purpose of this paper is to provide an overview of the scope and nature of this dataset and its potential utility as baseline data for future research.
