Hi,

I have a question about what is happening in this video at 00:25:02 -

What is the mechanism of filtration of beta-lines by Ni and Nb?.

Thanks!

K-beta radiation of an element with atomic Number Z is completely absorbed by an element of atomic number Z-1, thereby exciting the atoms of the absorbing element. Subsequently, the absorbing element returns to its ground state by a non-radiative process and hence, does not produce any additional radiation.
