What will be the decay constant of substance whose half life is 1 hour. Give your answer in (sec^-1).
Correct answer: C. 0.0001925
- A. 1925
- B. 0.001925
- C. 0.0001925
- D. 0.01925
Explanation
According to formula, Decay Constant = 0.693/ T1/2 T1/2 = half life of a substance Note 1 hour = 3600 seconds So, = 0.693 / 3600 = 1.925 10-4 ~ 0.0001925 sec-1

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
