Will a faraday cage stop gamma rays?

In summary, a faraday cage cannot be used to stop the radiation at the Japanese reactor because it only works on radio/microwaves, not on X-rays and gamma rays. Using pulsed DC current at the same frequency would also not be effective. Instead, substances with high density and thickness such as concrete and lead are more suitable for stopping high energy electromagnetic radiation. Lead, however, can produce high energy recoil electrons which can contribute to Bremsstrahlung radiation.

Can a faraday cage be used to stop the radiation at the Japanese reactor? If not why not? I know the frequencty is high but what if you pulsed DC current at the same frequency would that stop it?

Faraday cages work on radio/microwaves. X-rays and gamma rays penetrate matter.

I suggest one determine the frequencies of 10 keV, 100 keV, 1 MeV photons.

When it comes to stopping high energy electromagnetic radiation there is little better than thickness and/or density - concrete and lead come to mind as suitable substances. Lead has the density but also produces high energy compton recoil electrons that can subsequently lose energy via Bremsstrahlung radiation.
 

1. Will a faraday cage stop all types of gamma rays?

No, a faraday cage is not able to stop all types of gamma rays. It can only block electromagnetic radiation within a certain frequency range, which includes some but not all types of gamma rays.

2. How does a faraday cage protect against gamma rays?

A faraday cage works by creating a conductive shield that encloses the object or space inside. This shield deflects and absorbs incoming electromagnetic radiation, including gamma rays, thus protecting the contents inside the cage.

3. Can a faraday cage protect against all levels of gamma ray exposure?

No, a faraday cage can only provide protection up to a certain level of gamma ray exposure. If the intensity of the gamma rays is too high, it may still penetrate through the cage and cause damage to the contents inside.

4. Are there any materials that are more effective at stopping gamma rays than a faraday cage?

Yes, there are other materials such as lead or concrete that are more effective at stopping gamma rays than a faraday cage. However, a faraday cage is still a reliable and commonly used method of protection against gamma rays.

5. Can a faraday cage protect living organisms from gamma rays?

Yes, a faraday cage can protect living organisms from gamma rays. However, it is important to note that the cage must be properly constructed and grounded in order for it to effectively shield against gamma rays. Additionally, living organisms may still experience some exposure to gamma rays if they are outside of the cage or if the intensity of the radiation is too high.
