Decay constant( represented as lambda) can be determined or calculated as the inverse of the average lifetime of a given radioactive element before it decays.
The formula for average lifetime is as follows:
T= 0.693/ half-life( T 1/2)
= 0.693/30 = 0.0231 seconds
Therefore, the decay constant can be calculated as = 1/ T
= 1/0.0231 = 43.29 sec^-1.
Answer: The decay constant of the radioactive element is 43.29 sec^1 .
