Purpose of the Mean Lifetime Calculator

The primary purpose of the Mean Lifetime Calculator is to provide a user-friendly, scientifically accurate platform for calculating the mean lifetime of radioactive isotopes. It uses the formula τ = T₁/₂ / ln(2), where τ is the mean lifetime and T₁/₂ is the half-life. 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, ensuring alignment with peer-reviewed standards.

Scientific Foundation

The Mean Lifetime Calculator is grounded in nuclear physics, specifically the exponential decay law: N(t) = N₀ * e^(-t/τ), where τ is the mean lifetime, related to the half-life by τ = T₁/₂ / ln(2). The mean lifetime represents the average time a nucleus survives before decaying. 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 "Introduction to Nuclear Engineering" by John R. Lamarsh, ensuring accuracy and scientific rigor.
