We know that matter and anti matter annihilate each other if they come together. Then what would happen in a collision of a anti particle with our body?
What would happen to a person if she was submitted to a large number of antiparticles? Would her body disappear? If so, why doesn't it happen to us since we are subjected to a large number of antiparticles that come to the Earth such as the cosmic rays, solar wind, etc...Dale said:Such collisions of the human body with antimatter are used routinely in Positron Emission Tomography (PET) a standard medical imaging technology. In PET an unstable tracer is injected which emits positrons, which are antimatter electrons. These positrons annihilate with nearby electrons, and produce photons which are detected by the PET system.
It depends on how large a number you are talking about, and how rapid the exposure is. For gradual exposure you will die of radiation poisoning long before disappearing. For large rapid exposures think about nuclear weapons.kent davidge said:What would happen to a person if she was submitted to a large number of antiparticles? Would her body disappear?
Ok. Thank you.Dale said:It depends on how large a number you are talking about, and how rapid the exposure is. For gradual exposure you will die of radiation poisoning long before disappearing. For large rapid exposures think about nuclear weapons.
An antiparticle is the opposite counterpart of a particle, with opposite charge and other properties such as spin and magnetic moment. For example, the antiparticle of an electron is a positron, which has the same mass as an electron but with a positive charge.
Antiparticles can be created through high-energy collisions between particles or through certain types of radioactive decay. They can also be naturally produced in processes such as cosmic ray interactions with the Earth's atmosphere.
The discovery of antiparticles has greatly expanded our understanding of the fundamental laws of nature and has led to the development of theories such as quantum field theory and the standard model. Antiparticles also play a crucial role in understanding the universe and its origins.
Aside from having opposite charge, antiparticles also have opposite quantum numbers, such as baryon number and lepton number. They also have opposite spin and magnetic moment. In addition, when particles and antiparticles collide, they annihilate each other, releasing energy in the form of photons.
Yes, antiparticles have been used in medical imaging and cancer treatment through positron emission tomography (PET) scans and targeted radiation therapy. They have also been studied for potential use in energy production, although the technology is still in its early stages.
