radometer 

If anything flies off your dashboard while driving, your radometer has gone off.

Zude, slow down -- that's the third time the radometer's gone off.

Randometer 

A concept or device which measures the 'randomness' of a given event, object, behaviour, situation or being. It can be demonstrated using the lower arm placed horizontally with the hand of the other arm supporting the elbow of the 'randometer' arm. The randometer then moves from horizontal up to a potential 180 degrees to indicate the 'randomness' level required. It can also fluctuate as required during the randometer measuring process.

Use the Randometer when a dwarf unicycles past on a pink unicycle wearing pink wellington boots smoking a large pipe and humming the theme tune to Mighty Mouse.

radiometer

A radiometer or roentgenometer is a device for measuring the radiant flux (power) of electromagnetic radiation. Generally, a radiometer is an infrared radiation detector or an ultraviolet detector.1 Microwave radiometers operate in the microwave wavelengths.

While the term radiometer can refer to any device that measures electromagnetic radiation (e.g. light), the term is often used to refer specifically to a Crookes radiometer ("light-mill"), a device invented in 1873 in which a rotor (having vanes which are dark on one side, and light on the other) in a partial vacuum spins when exposed to light. A common belief (one originally held even by Crookes) is that the momentum of the absorbed light on the black faces makes the radiometer operate. If this were true, however, the radiometer would spin away from the non-black faces, since the photons bouncing off those faces impart more momentum than the photons absorbed on the black faces. Photons do exert radiation pressure on the faces, but those forces are dwarfed by other effects. The currently accepted explanation depends on having just the right degree of vacuum, and relates to the transfer of heat rather than the direct effect of photons. 23

A Nichols radiometer demonstrates photon pressure. It is much more sensitive than the Crookes radiometer and it operates in a complete vacuum, whereas operation of the Crookes radiometer requires an imperfect vacuum.

Rometer 

A thumbs up or thumbs down on how you are coping using the rometer. Use your first name eg how are you coping on the Billyromete?' Used mostly in lessons when your not allowed to talk and need emotional support.

radiometric dating

The scientific process of measuring the decay of elemental isotopes such as Carbon-14 to determine the age of organic or non-organic matter.

Person 1: Cool fossil! How old is it?
Person 2: I'm not sure. But we can find out from radiometric dating!
