Can you convert Half Life into Becquerels? How?
 
Physics news on Phys.org
They are different kinds of units. Half-life is defined for a specific radionuclide, independent of how much. Becquerel depends on the total quantity of the material.
 
One Becquerel is one nuclear decay per second. The half-life t½ is the time it takes half of the nuclei to decay. Related to t½ is the decay constant: t½ = ln(2)/λ. The significance of the decay constant λ is that it is the fractional rate per second at which nuclei are decaying:

dN/dt = - λ N

So if you multiply λ by the number of nuclei present, N, you'll get the number of decays per second, which is Becquerels.
 
Thank you, that made it clear.
 

Thread 'Toponium Discovered'

Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...

Thread 'Dirac-Delta from Normalization of Continuous Eigenfunctions'

I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
