Polonium-212 is formed by beta decay of bismuth-212.
In this case alpha particles are emitted.
Infrared radiation is emitted by the human skin. This type of radiation is invisible to the human eye but can be felt as heat.
The radiation emited is gamma ray
Alpha
Electromagnetic radiation in the form of thermal radiation is emitted as any substance, including iron, gets hot.
Electromagnetic radiation in the form of thermal radiation is emitted as any substance, including iron, gets hot.
Lead-208 is formed by alpha decay (emission of alpha particles) from polonium-212.
Two types of radiation are electromagnetic radiation, such as X-rays and microwaves, which travel in waves at the speed of light; and particle radiation, such as alpha and beta particles, which consist of high-speed particles emitted from a radioactive source.
gamma
Infrared radiation is the type of wave emitted by all warm bodies. This type of electromagnetic radiation has wavelengths longer than visible light and is commonly associated with heat.
Infrared radiation is the type of radiation that gets trapped on Earth's surface by the greenhouse effect. This radiation is emitted by the Earth's surface in response to the incoming solar radiation and is absorbed and re-emitted by greenhouse gases in the atmosphere, leading to the warming of the planet.
The infrared radiation emitted from a candle is a type of electromagnetic radiation that is not visible to the human eye. It is produced as a result of the heat generated by the candle flame and can be felt as warmth by our skin.
