Is alpha ionising or non ionising?
ionising
How can different electromagnetic energy be distinguished?
Electromagnetic energy comes in two basic forms: 1. Ionising 2. Non-ionising Ionising radiation has the capacity for its photons to knock components off atoms and change their chemical constitution. This is a feature of electromagnetic radiation with a short wavelength, from the short-wavelength end of the visible spectrum downwards. Non-ionising EM radiation has a longer wavelength, that is most of the visible spectrum, infra-red, microwaves and radio waves. It has insufficient energy in the photons to modify atoms. This type can only damage living tissues if it is too intense, and the mechanism of the damage is by a temperature rise only.
What type of radiation has the least ability to penetrate matter?
The Least penetrating form of radiation is Alpha as it only travels 10cm in air and is stopped by paper. Alpha is also the most ionising, Beta is less ionising still and Gamma is the least ionising as photons carry no charge so they have less effect.
What is the connection between the ionising power of radiation and its penetrating power?
Low ionising power results from great penetrating power.
Two types of energy that exsits on the electromagnetic spectrum?
the waves travelling with velocity of light and consisting of oscillating electric and magnetic fields perpendicular to each other and also perpendicular to the direction of their propagation are called electromagnetic waves.such waves with different ranges of frequency constitute an electromagnetic spectrum.these electromagnetic waves are classified in to different types depending on their wavelenth they areradio wavesmicro wavesinfrared lightvisible lightultraviolet lightx raysgamma rays
What are the dangers of non-ionising radiation?
Skin burns. Eye damage.
What are some examples of non ionising radiation?
mobile/cell phones microwaves radiation power lines
How much radiation does MRI emit?
There is no ionising radiation (e.g. X-rays) used in an MRI scan. It utilises radio-waves and a strong magnetic field but no radiation.
Is alpha ionising or non ionising?
ionising
What is a ionising and non-ionising radiation?
heat or light from the sun, microwaves from an oven, X rays from an X-ray tube, and gamma rays from radioactive elements

Is gamma ionising or non ionising?
no
What has the author H Moseley written?
H. Moseley has written: 'Non-ionising radiation' -- subject(s): Hospitals, Lasers, Microwaves, Nonionizing radiation, Physiological effect, Radiation, Non-Ionizing, Safety measures, Ultraviolet Rays
What kills micro-organisms?
Sterilization by various means such as steam sterilization (autoclave), dry heat (hot air oven), radiation (ionising & non-ionising),chemical methods etc. kills microorganisms.
What type of radiation has the least ability to penetrate matter?
The Least penetrating form of radiation is Alpha as it only travels 10cm in air and is stopped by paper. Alpha is also the most ionising, Beta is less ionising still and Gamma is the least ionising as photons carry no charge so they have less effect.
What is a good stopper of ionizing radiation?
If by ionising radiation you mean alpha radiation (the most ionising out of alpha, beta and gamma radiation) then about a millimetre of paper would stop it. alpha radiation ionises the molecules of anything it reaches, but can pass through very few things due to its immense ionising power. This includes human tissue, but in all honesty, a large dose of alpha radiation wouldn't do human tissue alot of good. In short, almost any material can stop ionising radiation.
How do you get energy from the sun and what kind of energy?
Energy from the Sun arrives through space as heat and light (and other things) as a form of electromagnetic radiation. There are two types of this, ionising and non-ionising. Below about ultra violet wavelengths the energy is non-ionising, which means it does no harm except possibly heating things up too much. At shorter wavelengths the energy is 'ionising', which means it could produce radiation sickness by altering atoms in the body. That is why too much sunshine occasionally causes skin cancer.
