41. Plastic Bags Thin sheets of plastic are used to make

items such as grocery bags. The sheets move under a

source of promethium-147, emitting beta particles. The

radiation intensity, measured under the plastic sheets,

is used to monitor the thickness of the plastic. During

this process, promethium changes into which element?

Respuesta :

Answer:

Promethium-147 changes into promethium-148.

Explanation:

Beta-decay: In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.

[tex]_{147}^{61}\textrm{Pm}\rightarrow _{148}^{61}\textrm{Pm}+_{-1}^0\beta[/tex]

During beta decay promethium-147 changes to promethium-148.
