SUMMARY

The half-life of strontium-90 is established as 28.0 years, which translates to a decay constant of 7.85 x 10-10 s-1. To calculate the decay constant, the formula k = ln(2) / half-life in seconds is utilized. Converting 28 years into seconds is essential for accurate computation. This discussion emphasizes the importance of unit conversion in radioactive decay calculations.
