The amount of radiation emitted by a hot body is directly proportional to the fourth power of its temperature (Stefan-Boltzmann law). Therefore, if the temperature of a hot body is increased by 50 units, the amount of radiation emitted will increase by a factor of (1+50/old temp)^4.
Low temperature objects like the human body emit infrared radiation. This type of electromagnetic radiation has longer wavelengths than visible light and is felt as heat.
Most of the radiation that produces a black body spectrum is emitted from the surface of the object itself. This radiation is a result of thermal vibrations of the atoms and molecules on the object's surface, which generate a continuous spectrum of electromagnetic radiation across various wavelengths.
The total radiation emitted by a black body is proportional to the fourth power of its absolute temperature according to Stefan-Boltzmann law. Therefore, if the absolute temperature of a black body is doubled, the total radiation emitted will increase by a factor of 16.
The heat emitted by a hot body depends on its temperature, surface area, and emissivity. The Stefan-Boltzmann law states that the total amount of heat radiation emitted by a body is directly proportional to the fourth power of its absolute temperature.

Gamma radiation
Most of the radiation that produces a black body spectrum is emitted from the surface of the object itself. This radiation is a result of thermal vibrations of the atoms and molecules on the object's surface, which generate a continuous spectrum of electromagnetic radiation across various wavelengths.
The temperature of the body. As the temperature of the body increases, the wavelength of the radiation emitted decreases, shifting towards shorter wavelengths. This relationship is described by Wien's displacement law.
ionizing radiation
The total radiation emitted by a black body is proportional to the fourth power of its absolute temperature according to Stefan-Boltzmann law. Therefore, if the absolute temperature of a black body is doubled, the total radiation emitted will increase by a factor of 16.

Infrared radiation. The human body emits infrared radiation as heat energy due to its normal metabolic processes. This type of radiation is not harmful and is commonly used in technologies such as thermal imaging.
Radiation is the type of body heat loss characterized by heat transfer from the surface of one object to the surface of another object without actual contact. This occurs through electromagnetic waves emitted by the warmer object and absorbed by the cooler object.
Gamma radiation is considered the most deadly type of radiation as it is highly penetrating and can easily damage tissues and cells in the body. This type of radiation is emitted during nuclear reactions and explosions.
