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 are the advantage of radiation?
Radiation can be beneficial in diagnosis and treatment of some medical conditions, ranging from X-rays to using specific isotopes to treat cancers. Gamma radiation can be used to sterilise equipment or food by killing bacteria.
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.
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 term is used to describe a perfect radiator and absorber of electromagnetic radiation?
blackbody
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 word is used to describe the particles and energy that are emitted by a nucleus?
radioactivity
Can radiation kill pancreatic cancer?
When ionising radiation interacts with living cells is usually kills these cells. Thus yes, radiation can kill pancreatic cells that are cancerous. However the radiation will also destroy healthy cells (and destroy the pancreas) so the amount of radiation given has to be low and well targeted. This is difficult to achieve and if any cancerous cells remain alive they will regrow the cancer.
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 is used to describe a random change in an animal's genes?
Its called mutation. It sometimes happens when something is exposed to radiation too long
What is the word used to describe the home in which you were born and raised?
my baby and teenage house
