Purpose of the Activity Decay Calculator

The primary purpose of the Activity Decay Calculator is to provide a user-friendly, scientifically accurate platform for calculating the remaining activity of radioactive isotopes after a specified time. It uses the exponential decay formula A = A₀ * e^(-λt), where A is the final activity, A₀ is the initial activity, λ is the decay constant, and t is time. Built with verified nuclear data, it serves as an educational aid, a research tool, and a practical resource for professionals in nuclear physics, medical physics, and radiation safety.

Scientific Foundation

The Activity Decay Calculator is grounded in nuclear physics, specifically the exponential decay law: A = A₀ * e^(-λt), where the decay constant λ = ln(2) / T₁/₂, and T₁/₂ is the half-life. Activity is measured in becquerels (1 Bq = 1 decay/s). The tool uses standard half-life values from nuclear data sources like the National Nuclear Data Center (e.g., 5730 years for Carbon-14, 8.02 days for Iodine-131). Calculations align with methodologies in texts like "Fundamentals of Nuclear Science and Engineering" by J. Kenneth Shultis, ensuring accuracy and scientific rigor.
