"X-ray fluorescence (XRF) is a widely used analytical technique in the field of photochemistry and geochemistry for elemental analysis of various materials including rocks, minerals, soils, sediments and some organic material. It provides quantitative data and information about the elemental composition and concentrations present in these samples. This proposal will delve into the fundamentals and basics of XRF and its applications within geochemistry and attempt to address a 

XRF operates on photochemical principles and the interaction between high-energy X-rays and the electrons within the atom of a sample. When a sample is bombarded with X-rays, inner-shell electrons of the atoms get excited and jump to higher energy levels or orbitals within the atom. Subsequently, these electrons then return to lower energy levels and emit high-energy radiation in the form of fluorescent X-rays. From here the X-ray fluorescence analysis process involves detecting and integrating the emitted characteristic lines to determine their intensities. These intensities are then converted into elemental concentrations to determine the make-up of the specific sample. Earth materials, such as rocks and soil, are composed of a wide range of elemental minerals such as Li, Fe, etc. with varying compositions and structures. These complexities influence the behavior of light in intricate ways. However, through X-ray techniques like XRF, it becomes possible to identify and analyze these elements based on the unique emitted radiation associated with their specific compositions under certain conditions.

My aim is to explore the influence of photochemical effects on the samples being analyzed including the reliability, limitations and precision of XRF analysis in the context of geochemical and alternative studies. By exploring the reliability and limitations associated with photochemical alterations, we seek to provide a comprehensive understanding of the potential effects on the integrity and interpretation of XRF analytical data and the possible effects it may or my not have on the physical and chemical structures of the 

Temitope D. (2018) work provides a comprehensive review and overview of X-ray fluorescence (XRF) applications in the investigation of the composition of earth materials. His work covers the broader applications of XRF in geochemical studies, including discussions on methodologies, instrumentation and data interpretation techniques used within the field. It offers insights into the role of XRF in assessing elemental compositions and variations in earth materials, which will be essential for understanding the influence of photochemical alterations and interactions within XRF application and use. 

The study by Menachekanian et al. (2018) focuses specifically on investigating the photochemical effects of micro-XRF analysis on common geochemical compounds. This paper will aid in addressing the topic of interest and provides valuable insights into the potential alterations that may occur during XRF analysis due to photochemical reactions. Understanding the specific effects of photochemical changes on different geochemical compounds and elements will be crucial for assessing the accuracy and reliability of XRF measurements in a practical and applicable context. 

Caporale’s (2018) research evaluates the performance and limitations of both portable-XRF and conventional laboratory-based XRF techniques for monitoring metal pollution in soils. It offers relevant information on the performance and limitations of XRF techniques in geochemical studies. Understanding the capabilities and constraints of XRF in differentiating metal pollution sources in soils can contribute to our understanding of the broader issues related to accuracy and reliability of XRF analysis.

In addition to examining XRF applications in geochemistry such as minerals and soil it is also essential to explore the relevance and potential limitations when analyzing organic materials and sediments. One relevant study conducted by Jack Longman (2018) investigates the utilization of XRF core scanning on peat and other highly organic sediment formations. This research will provide valuable insights into the challenges and considerations specific to the organic component when applying XRF analysis. These limitations may include variations in sample composition, difficulty in achieving accurate measurements and potential interference or misinterpretation from organic compounds on the XRF signal.
