How is the process of radiation?
Radiation is the process by which energy is emitted as either particles or waves.
Broadly, it can take the form of sound, heat, or light.
However, most people generally use it to refer to radiation from electromagnetic waves, ranging from radio waves, though the visible light spectrum, and up through to gamma waves..
What are the basic concepts of radiation physics?
Radiation is classified into two main categories: non-ionizing and ionizing, depending on its ability to ionize matter.
The ionisation potential of atoms, i.e., the minimum energy required to ionize an atom, ranges from a few eV for alkali elements to 24.5 eV for helium (noble gas)..
What is radiation and where does it occur?
Radiation is energy that comes from a source and travels through space at the speed of light.
This energy has an electric field and a magnetic field associated with it, and has wave-like properties.
You could also call radiation “electromagnetic waves”..

What is the purpose of radiation in physics?
Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity.
In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others..

Where do you find radiation?
By far the largest source of natural radiation exposure comes from varying amounts of uranium and thorium in the soil around the world.
The radiation exposure due to cosmic rays is very dependent on altitude, and slightly on latitude: people who travel by air, thereby, increase their exposure to radiation..
Why should we study radiation?
Today, radiation is a common and valuable tool in medicine, research and industry.
It is used in medicine to diagnose illnesses, and in high doses, to treat diseases such as cancer.
Also, high doses of radiation are used to kill harmful bacteria in food and to extend the shelf life of fresh produce..
- Energy emitted from a source is generally referred to as radiation.
Examples include heat or light from the sun, microwaves from an oven, X rays from an X-ray tube and gamma rays from radioactive elements.
Ionizing radiation can remove electrons from the atoms, i.e. it can ionize atoms. - Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness").
It can also result in long-term health effects such as cancer and cardiovascular disease. - Inserting the proper shielding (e.g., lead, concrete, or special plastic shields depending on the type of radiation) between a worker and a radiation source will greatly reduce or eliminate the dose received by the worker.
- Radiation can damage the DNA in our cells.
High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI).
High doses of radiation could also lead to cancer later in life.
