The electrical potential and/or current on the plate can then be predicted using this information along with the known data of the radiation level of the substance, plate geometry, and substance density. In summary, the electrical potential and/or current on a copper plate can be predicted by calculating the average number of electrons released per second from the given data about the radioactive substance and plate.

Hello. Say that I were to take a beta emitting radioactive substance, crush it up, and apply it to a copper plate. Is there a way for me to predict the electrical potential and/or current on the plate (due to the emitted electrons) based on known data, such as radiation level of the substance, plate geometry, substance density, etc?

You can calculate the average number of electrons released per second from the equation:
dN/dT=-xN
x= decay constant=0.693/half life,N= number of radioactive atoms present in your sample.
 

FAQ: Beta Decay & Electron Emission Potential

What is Beta Decay?

Beta decay is a type of radioactive decay in which a nucleus emits a beta particle (an electron or positron) to become more stable.

How does Beta Decay occur?

Beta decay occurs when an unstable nucleus has too many or too few neutrons compared to protons, causing it to emit a beta particle in order to achieve a more stable ratio.

What is the difference between Beta- and Beta+ Decay?

Beta- decay occurs when a nucleus emits an electron, while beta+ decay occurs when a nucleus emits a positron (a positively charged electron). They both result in a more stable nucleus, but with a different number of protons and neutrons.

What is Electron Emission Potential?

Electron emission potential is the amount of energy required to remove an electron from an atom. In beta decay, this potential is released as the electron (or positron) is emitted from the nucleus.

How is Beta Decay used in practical applications?

Beta decay is used in various applications, such as in nuclear power plants to generate electricity, in medical imaging to diagnose and treat diseases, and in carbon dating to determine the age of artifacts and fossils.
