Abstract

Slice Thickness is the thickness of the image slices on the CT Scan results and is one of the parameters that affect the CT Scan image. This study aims to analyze the image quality of the use of Slice Thickness variations in the CT scan of the head by paying attention to 3 aspects assessed, namely Spatial Resolution, Contrast Resolution, and Noise. This research was conducted by reconstructing the CT scan of the head into 3 types of images, namely Slice Thickness 3 mm, 5 mm, and 7 mm. The results of this study are CT scan images with a slice thickness of 3 mm have an average Spatial Resolution (3.71), Contrast Resolution (3.42), and Noise (3.85) Slice Thickness 5 mm has an average Spatial Resolution (2.71), Contrast Resolution (2.57), and Noise (3.28) and Slice Thickness 7 mm has an average Spatial Resolution (1.57), Contrast Resolution (1.71), and Noise (2 ,14). The best image quality is obtained by using a slice thickness of 3 cm.

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

Proteksi radiasi adalah cabang ilmu pengetahuan yang berkaitan dengan teknik kesehatan lingkungan yaitu tentang proteksi yang perlu di berikan kepada seseorang atau sekelompok orang ataupun kepada keturunannya terhadap kemungkinan yang merugikan kesehatan akibat paparan radiasi. Tujuan penelitian ini untuk mengetahui bagaimana proteksi radiasi bagi pekerja radiasi di Instalasi Radiologi Rumah Sakit Universitas Hasanuddin Makassar. Jenis penelitian yang digunakan yaitu penelitian kulitatif dengan metode deskriptif, yaitu memberikan gambaran proteksi radiasi bagi pekerja radiasi di Instalasi Radiologi Rumah sakit Unhas Makassar. Sampel dalam penelitian ini seluruh tindakan proteksi radiasi yang dilakukan terhadap pekerja radiasi. Teknik pengambilan sampel dilakukan dengan cara mengumpumpulkan data tersebut yang didasarkan pada fakta dengan membaca literatur-literatur yang berkaitan dengan permasalahan penelitian Variabel dalam penelitian ini adalah persyaratan proteksi radiasi yang telah dirangkum menjadi personil, pelatihan proteksi radiasi, pemantauan kesehatan, rekaman, pemantauan dosis, bangunan fasilitas, peralatan proteksi radiasi, dan uji kesesuain. Hasil penelitian menunjukkan bahwa Hasil penelitian proteksi radiasi bagi pekerja radiasi di Instalasi Radiologi Rumah Sakit Universitas Hasanuddin Makassar dapat dinyatakan terpenuhinya tindakan proteksi radiasi bagi pekerja radiasi baik dari radiasi primer maupun radiasi sekunder dengan adanya hasil dari paparan radiasi.

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.
