SUMMARY
Radioactive materials are deemed safe when their activity decreases to below 0.1% of the initial value, which corresponds to 10 half-lives. The calculation for determining the number of half-lives (n) involves the equation 1/2^n = 1/1000. By applying logarithmic functions, specifically x = -log2(0.001), it is established that n equals 10, confirming the safety threshold for radioactive decay.
