Final answer:
Humans emit infrared radiation naturally as a form of heat, which is part of the electromagnetic spectrum. Gamma rays are a higher-energy form of radiation not emitted by humans under normal conditions but can be produced by radioactive substances and astronomical phenomena.
Step-by-step explanation:
The type of radiation that you are emitting right now is primarily infrared radiation. This is because all objects, including humans, emit radiation primarily in the form of heat or infrared energy, which is part of the electromagnetic (EM) spectrum. The radiation each of us emits is much less energetic than other forms of EM radiation such as gamma rays or X-rays. Gamma rays, being the most energetic form of EM radiation, are produced by radioactive decay and certain astronomical events but are not emitted by humans under normal conditions. Instead, these high-energy forms of radiation, like gamma rays and X-rays, generally require high-energy processes or elements to be produced.
Governed by laws of physics and black body radiation principles, the infrared radiation emitted by a person is generally harmless and very different from the ionizing radiation such as gamma rays that can have profound effects on living tissues.
