Uranium-238 Decay Activity Simulation
This simulation demonstrates the calculation of activity for a 1g sample of Uranium-238, which undergoes alpha decay with a half-life of 4.5 billion years. The activity (decay rate) is calculated using the formula:
R = λN = (0.693/T1/2) × N
Where λ is the decay constant, N is the number of radioactive atoms, and T1/2 is the half-life.
