lead
No type of electromagnetic radiation has any effect on any other type. In order to 'stop' it, you need a material that absorbs it.
A brick wall blocks light from passing through it due to its thick and dense structure. A wooden door absorbs light as the photons get absorbed by the atoms in the wood, preventing light from passing through. A bookshelf made of metal will stop or absorb light due to its solid and non-transparent material.
To stop a laser, you would need to block its path with a material that can absorb or reflect the laser beam, such as a metal sheet or a mirror. Additionally, turning off the power source of the laser would also stop it from emitting light.
Nothing stops 'Gamma' rays, however you can block it with 1/2" of lead will prevent 1/2 of the radiation and then it will continue until it is and insignificant amount to record. Hope this was helpful.
What substance that initiates action through receptor
No there is no material discovered which can stop the penetration of gamma radiations
Lead is commonly used to stop radiation due to its high density and ability to absorb and attenuate radiation particles. Lead shielding is commonly used in medical facilities, nuclear facilities, and other settings where radiation protection is necessary.
Metal
You can reflect it, absorb it or even diffract it (a bit).
inhibitors
They can stop metabolic processes in extremes of cold. They have dark pigments to help them absorb heat. They can absorb moisture form snow and ice.
Beta radiation can be stopped by using materials such as plastic, aluminum, or glass. These materials absorb the beta particles and prevent them from penetrating further. However, the exact material and thickness required for effective shielding depend on the energy of the beta particles.
