Decay rate for Radium-228 is 0.01205
Step-by-step explanation:
The half life of radium-228 is 5.75 years. We need to find the decay rate for radium.
The formula used is:
Where N₀ = amount of radioactive particles at time = 0
N_t = amount of radioactive particles are time (t)
λ = rate of decay constant
t = time
We are given half life so, =0.5
t= 5.75 years
We need to find λ
Putting values in formula and solving:
So, Decay rate for Radium-228 is 0.01205.
