What are the two types of radiation?
There are two kinds of radiation: non-ionizing radiation and ionizing radiation.
Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms.
Examples of this kind of radiation are radio waves, visible light and microwaves..
What is the difference between natural and artificial background radiation?
Natural background radiation includes radiation produced by the Sun, lightnings, primordial radioisotopes or supernova explosions etc. Man-Made Sources of Radiation. Man-made sources include medical uses of radiation, residues from nuclear tests, industrial uses of radiation etc.
How dangerous is background radiation?
Humans encounter background radiation every day. Most of the radiation people get exposed to does not occur in high enough concentrations to cause any ill effects. If the background radiation rises above acceptable levels, the affected area experiences higher incidents of certain diseases.
What can affect background radiation?
Background radiation varies from place to place and over time, depending on the amount of naturally-occurring radioactive elements in soil, water and air. Weather conditions also affect radiation levels, as snow cover may shield these elements, and radioactive particulates can wash out of the air during rain storms.
What are 3 sources of radiation?
Natural background radiation comes from the following three sources:Cosmic Radiation.Terrestrial Radiation.Internal Radiation.
What are the 7 types of radiation?
There are seven natural forms of EMR. Gamma rays have the highest energy and shortest wavelength. Then come X-rays, ultraviolet light, visible light, infrared radiation and microwave radiation. Finally, radio waves have the lowest energy and longest wavelength.
What is the greatest source of 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.
What are the natural sources of radiation?
The composition of the earth’s crust is a major source of natural radiation. The main contributors are natural deposits of uranium, potassium and thorium which, in the process of natural decay, release small amounts of ionizing radiation.
What are two sources of background radiation?
Natural sources of background radiation include:cosmic rays – radiation that reaches the Earth from space.rocks and soil – some rocks are radioactive and give off radioactive radon gas.living things – plants absorb radioactive materials from the soil and these pass up the food chain.
Can you protect yourself from background radiation?
Use Time Distance and Shielding to Protect Yourself. Putting distance and shielding between you and a radiation source is an immediately effective way of reducing your exposure. Reducing the time you are being exposed is another way. Use a Respirator or Face Mask if You are exposed to airborne sources.
How is background radiation detected?
Background radiation level can be found as follows:With no radioactive sources in the room start a stopwatch and GM tube (with counter) at the same time.After 60 seconds, stop the GM tube and counter and record the number of counts in 60 seconds.Calculate background activity in the room.More items…
What materials can block radiation?
Non-lead shielding materials are manufactured with additives and binders mixed with attenuating heavy metals that fall into the same category of materials as lead that also absorb or block radiation. These metals may include tin (Sn), antimony (Sb), tungsten (W) bismuth (Bi) or other elements.
What is considered background radiation?
The natural radiation that is always present in the environment. It includes cosmic radiation which comes from the sun and stars, terrestrial radiation which comes from the Earth, and internal radiation which exists in all living things.
What are the 4 types of radiation?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.
What are sources of ionizing radiation?
Ionizing radiation is a type of energy released by atoms in the form of electromagnetic waves or particles. People are exposed to natural sources of ionizing radiation, such as in soil, water, and vegetation, as well as in human-made sources, such as x-rays and medical devices.
