This PowerPoint explores radioactive decay, covering the random disintegration of unstable nuclei into more stable forms. It explains key concepts such as parent and daughter nuclei, alpha and beta decay processes, and nuclear equations. The presentation introduces half-life, radioactive decay curves, and activity measurements. Real-world examples, including Chernobyl’s impact, highlight the effects of ionizing radiation on living organisms. Safety precautions in labs and industries are also detailed, emphasizing protective measures against exposure.
