Abstract
Improving scientific literacy among high school students in Indonesia remains a challenge, prompting initiatives to enhance this skill. This research aims to develop a nuclear radiation practicum module for high school students and analyze environmental radiation dose rates. The study involves comparing radiation measurements using various tools and evaluating the impact of environmental background conditions on these measurements. It utilizes Cs-137 (Cesium 137) sources at different distances and with different shielding materials. The ADDIE approach-Analysis, Design, Development, Implementation, and Evaluation-guides the module development process.The study is limited to the development stage, focusing on creating models for the measurement process, mapping, and comparing tools and practicum materials. Radiation dose rate measurements were conducted at the Bandung Institute of Technology at 10 points with instrument heights of 0 cm and 100 cm from the ground, using GMC 500+ and Pocket Geiger tools. Results show that the GMC 500+ tool measured an average radiation dose rate of 0.1365 \pm 0.0160 \mu Sv/hour at 0 cm height and 0.1207\pm0.0163 \muSv/hour at 100 cm height. The Pocket Geiger tool recorded an average dose rate of 0.052\pm0.0154 \mu Sv/hour at 0 cm and 0.043\pm0.0176 \mu Sv/hour at 100 cm height. Measurements on different background surfaces (granite floors, paving blocks, soil, concrete, grass, and asphalt). Measurements using the Cs-137 source determine the effect of distance on the radiation source and shielding material, with distance variations from 0 cm to 100 cm and the use of shielding material stored between the source and the detectorThe final product is a validated nuclear radiation practicum module, which received positive feedback from material and media experts, peers, and high school physics teachers, indicating its readiness for implementation.
