A hospital prepares a 100mg supply of technetium-99m which has a half-life of 6 hours. what is the decay factor?

For a half - life, the formula is

A (t) = A0 (0.5) ^ (t / t_0.5)

where A (t) is the amount of substance at time t

A0 is the initial amount of subtance

t_0.5 is the time it will reduce its amount to half

t is the time

substitute the given to the formula

A (t) = 100 (0.5) ^ (t/6)

so the decay factor is 0.5^ (t/6)
