The decay constant can be calculated using the formula:
λ = (ln(N0/Nt))/t
Where:
λ = decay constant
N0 = initial activity
Nt = final activity
t = time interval
Substituting the given values:
N0 = 2000 Bq
Nt = 1000 Bq
t = 10^6 sec
λ = (ln(2000/1000))/10^6
λ = 6.93 x 10^-7 s^-1
Therefore, the decay constant is 6.93 x 10^-7 s^-1.
