प्रश्न

The half-life of a certain radioactive element is 3.465 days. Find its disintegration constant.

एक पंक्ति में उत्तर

उत्तर

TH = 3.465 days, λ = ?

We know that 
λ = 0.693TH

λ = 0.6933.465×24×60×60 S-1

λ = 2.31 x 10-6 s-1

Radioactive isotopes are produced in a nuclear physics experiment at a constant rate dN/dt = R.
