This is a wide ranging question, there are hundreds of radioactive isotopes, all with their own characteristics of half life, type of radiation, and energies produced. The common feature is that the nucleus of an active isotope is in an unstable condition and emits radiation to achieve a more stable one. Often there are long chains of daughter products before a fully stable isotope is reached, like lead for example. I recommend you to look up in Wikipedia articles such as Radioactivity.
Yes, electromagnetic radiation weakens as you move further away from the source because it follows the inverse square law, which means the intensity of radiation decreases with the square of the distance from the source. So, the further you are from the source, the weaker the radiation will be.
No, radiation does not rise. Radiation can travel in all directions from its source, with its behavior dependent on the type of radiation and the surrounding environment.
The Sun is the primary source of radiation for both the Earth's atmosphere and the greenhouse effect. Solar radiation enters the atmosphere, warms the Earth's surface, and is re-radiated as infrared radiation. Greenhouse gases in the atmosphere trap some of this infrared radiation, leading to the greenhouse effect.
On the amount of radiation emitted; on how close the individual is to the source of the radiation; on any objects in between which might absorb part of the radiation.
the energy source is sun. Photosynthesis need sun as a energy source.
Cosmic radiation External terrestrial and internal radiation
No, doubling the source of radioactivity will not halve the radiation intensity. Radiation intensity is directly proportional to the amount of radioactive material present. So doubling the source will double the radiation intensity.
The relationship between the intensity of radiation and the distance from the source, as described by the inverse square law, states that the intensity of radiation decreases as the distance from the source increases. This means that the further away you are from the source of radiation, the lower the intensity of radiation you will be exposed to.
Curling irons are not a source of radiation. They use heat to style the hair, which is a form of thermal energy, not radiation.
diagnostic radiation
The source doesn't care how far you are from it, or whether you're even there, andthere's no relationship between that and the intensity of the radiation it gives off.However, the intensity of the radiation that you receivefrom it is inversely proportionalto the square of your distance from it ... same math as for gravity.
The fundamental source of electromagnetic radiation is the acceleration of charged particles. When charged particles are accelerated, they create changing electric and magnetic fields that propagate as waves through space, resulting in electromagnetic radiation.
The three elements associated with radiation exposure are time, distance, and shielding. Increasing the time spent near a radiation source, reducing the distance from the source, and using appropriate shielding can all affect the level of radiation exposure.
Radiation strength refers to the amount of energy emitted by a radiation source per unit of time. It is a measure of the intensity or power of the radiation being emitted. The strength of radiation can vary depending on the type of radiation source and the distance from the source.
Moving away from an ionizing source of radiation typically decreases the intensity of radiation exposure you receive. The further you move from the source, the lower the dose of radiation you are exposed to.
A point source is a concentrated source of radiation or pollution that has a limited area.
Infrared radiation is a property of energy transfer that is always away from the source.
