Sulfur is one of the most interactive elements of our atmosphere, oceans, and overall biogeochemical processes. It is abundant in our oceans, sea spray aerosols, and oceanic sediments. It’s presence in the atmosphere, rivers, biomass, and soils is less predominant but still significant in providing linkages between earth’s major reservoirs. Since it possesses multiple valence states ranging from (-1 to +6), it can exist in a multitude of stable redox states such as carbonyl sulfide, hydrogen sulfide, elemental sulfur, or sulphate. It is because of this versatility that sulfur gains importance when studying cosmogenic production of sulfur that exists in the atmosphere where it’s behavior can provide deeper insight to atmospheric chemical processes as well as sources of changes in climate. Sulfur possesses four stable isotopic states (32S, 33S, 34S, and 36S) and one unstable nuclide (35S). Radiogenic 35S has a half-life of approximately 87.4 days making it an ideal tracer for atmospheric chemical evolution and dynamics. It is naturally produced by nuclear spallation of 40Ar in the upper atmosphere due to high energy cosmic rays and transported down by stratospheric to tropospheric intrusions. It can also be produced by 35Cl neutron capture because of thermal neutrons reacting with abundant chlorine targets in seawater. Upon decay it emits a low energy beta particle (Emax = 0.167 MeV), an antineutrino to conserve spin, and a 35Cl atom. Due to the very low energy of the emitted beta particle and its low abundance in the atmosphere, it has not been utilized in detail until recently. By use of an ultra-low level liquid scintillation counter, it is possible to accurately detect 35S in aerosol samples to track its behavior during major solar and climatic events even though the actual number of radioactive atoms is small. Solar cycle 25 and El Niño Southern Oscillations counterpart, La Niña, have major impacts on the fragile present-day climate. La Niña has been linked to several catastrophic wildfires (Shaheen et al, 2014), severe drought, and abnormal rainfall in the past and there is uncertainty when predicting this phenomenon. The production of radionuclides such as 35S and 14C is also altered by solar wind intensity that varies on 11-year cycles due to the sun’s changing magnetic field. Combined with increased cosmic rays due to a decreased solar magnetic field, 35S can afford us insight as to what is happening in the atmosphere at a deep level thus, allowing us to better prepare and adjust accordingly in response to impactful climatic events such as La Niña as well as record solar phenomena. During the time of this study, the world also witnessed the development of a Russian invasion of Ukraine. Amidst the attack on Ukraine, a nuclear power plant in southern Ukraine was targeted and overtaken by Russia on March 4, 2022 (Castelvecchi, 2022). The Zaporizhzhya Nuclear Power Plant (ZNPP) had not reported irregular levels of radiation in the area and the damage was said to be minimal. The ZNPP is near bodies of water with high salinity making production of 35S by neutron capture a possibility. Detection of irregular 35S readings would be indicative of possible damage to a reactor core emitting a noticeable neutron flux. This detection method was applied following the incident that occurred at Fukushima Daiichi confirming leakage of harmful radiation and proving the extent of its reach. This method and its application will be discussed in further detail later in this study.
