What else can I help you with?
A synthetic element that is used in smoke detectors is?
Americium-241 this is an emitter of alpha radiation, which is used in smoke detectors as it is very ionising and will not be able to travel through smoke. Therefore, in a fire the detector will not receive any alpha radiation and hence the alarm will go off.
What is the term used to describe?
It is used to describe a 2.4G radio. It is also used to describe items for buggy racing and stuff like that for buggies and racing. That is basically all the term is used to describe.
What process is used when Thermal energy moving from the sun to earth?
The process used for the sun's heat energy to reach Earth is called thermal radiation. This electromagnetic radiation is caused by charged particles' motion in the Sun.
Is opening oven door radiation?
If oven was recently used, heat will radiate when opened.Most of the heat escaping from an oven when the door is opened is by convection, not radiation.
What word is used to describe a gap between two neurones?
The term used to describe the gap between two neurons is synapse, or synaptic junction.
What is the term used to describe elements that give out ionising radiation?
Radioactive elements.
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.
What else can Ionising Radiation be Used for?
X-Rays, smoke detectors, sterilizing medical supplies, destroying cancer, CAT scans of the body.
What spectrum is used to describe differences in radiation?
ople
Spectrum that is used to describe differences in radiation?
The electromagnetic spectrum
What wavelengths of electromagnetic radiation possess sufficient energy to be able to kill microorganisms?
The type of radiation that causes radiation sickness is officially called 'ionising radiation', which means that it consists of particles that carry enough energy to knock electrons out of ordinary atoms, making them electrically charged or ionised. There is also harmless radiation such as normal heat and radio waves, that is non-ionising radiation, and those are harmful only in their heating effect if they are too intense.
What is the connection between x-rays and radiation?
Radio waves, Microwaves, Infrared, Visible Light, Ultraviolet, X-Rays, Gamma Rays etc. are all Electromagnetic radiation, just at different frequencies.In physics, radiation is any process by which energy travels from one body to another.When most people hear radiation they think of ionising radiation, which is a radiation that is strong enough to ionize atoms.X-Rays are both Electromagnetic radiation and ionising radiation, because of the later it is a health hazard.http://en.wikipedia.org/wiki/Radiography
How much radiation does MRI emit?
MRI does not emit ionizing radiation like X-rays or CT scans. Instead, it uses a magnetic field and radio waves to create detailed images of the body's internal structures without exposing the patient to harmful radiation.
What is a radiation are called?
A region of space where radiation is present is called a radiation zone. This term is often used in the context of astrophysics to describe regions in space where high-energy particles or electromagnetic radiation are prevalent.
What is the uses of ionising radiations?
Ionizing radiation is used in various beneficial applications, including medical imaging (X-rays, CT scans), cancer treatment (radiation therapy), sterilization of medical equipment, food irradiation for preservation, and industrial applications such as thickness gauging and quality control in manufacturing processes.
What word is used to describe the particles and energy that are emitted by a nucleus?
radioactivity
What do you call the radiation that is always present?
Background radiation is the term used to describe the low levels of ionizing radiation that are constantly present in the environment from both natural and man-made sources.
