A radioactive isotope has an activity of 9.60 mCi. After 3.75 hours the activity is 7.39 mCi. What is the half-life of the isotope

Respuesta :

For a radioactive isotope has an activity of 9.60 mCi.  , the half-life of the isotope is mathematically given as

t0.5 = 23893 s

What is the half-life of the isotope?

Generally, the equation for the half-life  is mathematically given as

t0.5=T*0.693

Where

A = A0 e^(-t/T)

t/T = lnA0/A

3.75 hours/T=ln 9.60/7.39

T = 34478.5 s

Therefore

t1/2 = TX0.693

t0.5 = 23893 s

In conclusion, the half life

t0.5 = 23893 s
