How do Fusion/Fission Gamma Rays Compare?

In summary, the conversation discusses concerns about the amount of shielding needed for a nuclear reactor, particularly in regards to aneutronic He3-He3 fusion. The possibility of this fusion producing less energetic photons than fission is explored, as well as the lack of information about the production of gammas or neutrons. The use of He3 is also mentioned, with the suggestion to consider alternative reactions.

My concerns are all about how much shielding would be needed for a nuclear reactor. Would aneutronic He3-He3 fusion produce less energetic photons than fission to be more easily used in more mobile reactors? Obviously very few neutrons are made in this reaction so that leaves the high energy photons the remaining concern.

More of a sci-fi interest, the power armour in the fallout 4 have almost no shielding for the "fusion cores".

I do not have information about He3+He3 that produces gammas or neutrons, only X rays (very easy to shield). (perhaps it emits but there is no information)

Very good reaction, but where is the He3? It is impossible to buy, you should use another reaction to generate it
 

1. How is the energy released by fusion gamma rays different from that of fission gamma rays?

The energy released by fusion gamma rays is much higher than that of fission gamma rays. This is because fusion involves combining two smaller nuclei to form a larger one, leading to a greater release of energy.

2. Which process produces more gamma rays: fusion or fission?

Fusion produces more gamma rays than fission. This is because fusion reactions involve the conversion of a larger amount of mass into energy, resulting in a larger number of gamma rays being released.

3. How are fusion and fission gamma rays used in practical applications?

Fusion gamma rays are used in nuclear power plants to generate electricity, while fission gamma rays are used in medical treatments such as radiation therapy for cancer patients.

4. Are fusion gamma rays more dangerous than fission gamma rays?

In terms of radiation exposure, both fusion and fission gamma rays can be dangerous if not properly controlled. However, fusion reactions produce shorter-lived radioactive products, making it less hazardous in the long term compared to fission reactions.

5. Can fusion and fission reactions occur simultaneously?

Yes, fusion and fission reactions can occur simultaneously in certain types of nuclear reactions. This is known as a "hybrid" reaction and is currently being studied as a potential energy source for the future.
