Radioactive Decay: Isotope A to B in 1 Hour

Click For Summary
SUMMARY

The discussion centers on the decay of isotope A to isotope B within one hour. It establishes that in the case of alpha decay, the decay process results in the loss of a helium nucleus, leading to a slight reduction in the mass of isotope B. In contrast, beta and gamma decay result in negligible mass changes, confirming that approximately 10 mg of isotope A will yield about 10 mg of isotope B after one hour.

PREREQUISITES
  • Understanding of radioactive decay types: alpha, beta, and gamma decay

If isotope A decays to isotope B.
Does it mean that if within 1 hour we have 10 mg of A that decays, do we get exactly 10 mg of B after one hour?

thanks

That depends. In alpha decay, isotope A would decay to isotope B plus a helium nucleus, which escapes, so isotope B would weigh slightly less. In beta and gamma decay, the mass change is insignificant.
 
This is Beta decay.

so I guess 10 mg of A will give me approx. 10 mg of B.
