Abstract

Dating ancient human fossils is a crucial component in reconstructing hominin evolution and migration. This article reviews the basic principles and applications of various radiometric dating techniques, including radiocarbon (14C), potassium-argon (K-Ar), uranium-series (U-Pb, U-Th), and advanced methods such as accelerator mass spectrometry (AMS) and laser ablation ICP-MS through a systematic literature review of primary and secondary sources. Data synthesis shows that the 14C method is effective for materials up to ~50,000 years old, at the same time K-Ar and U-Pb/Th are suitable for older geological age ranges (hundreds of thousands to millions of years). Improved accuracy is supported by submicroscopic isotope analysis technology; however, the challenges of sample contamination and limited amounts of authentic material still limit its widespread application. These findings underscore the importance of a multi-method approach to obtain reliable absolute ages for human fossils and provide recommendations for refining sample handling procedures and integrating relative data (stratigraphy, magnetostratigraphy) for more comprehensive temporal contextualization.

Abstract

Nuclear physics is the study of atomic nuclei and the particles and phenomena associated with them. It plays a vital role in technology, particularly in the medical field. One medical device that applies the principles of nuclear physics is Positron Emission Tomography (PET), an imaging technology used effectively for diagnosing various diseases. The purpose of this article is to examine the use of nuclear physics in PET for medical diagnosis, including a review of the nuclear-physics mechanisms behind PET itself. This article highlights the importance of a thorough understanding of nuclear physics in medical diagnostics.
