LET’S GET SCIENC”E”
An occultation is a type of this astronomical event
What is an eclipse?
The world’s more than 400 nuclear power plants use this process of splitting an atom in two to create energy
What is fission?
This word means to “give out” radiation
What is emit?
Another word for the flow of electric charge is
What is current?
These three primary types of nuclear radiation are identified by Greek letters
What are alpha, beta and gamma?
In science talk, it’s a gamete

The diameter of the nucleus is a quadrillionth of this unit
What is a metre?
This word means to “take in” radiation
What is absorb?
The letter that represents charge is
What is Q?
eV for short, this unit of energy used in nuclear physics is so small, a trillion of them equals the motion of a mosquito
What is an electron volt?
The adrenal and the thyroid are among these glands that regulate your body’s processes by secreting hormones

A gamma particle is a high-energy one of these light particles emitted during radioactive disintegration
What is a photon?
The type of radiation that all objects emit, in differing amounts
What is infrared?
The letter that represents current is
What is I?
The “L” in LHC means large, the “H” is for hadrons and “C” refers to this what happens when the particles move in different directions
What is collide?
In physics, it’s the ability of a deformed body to return to its original size and shape

This word, once used by alchemists, today means the changing of one element into another by a nuclear reaction
What is transmutation?
This coloured surface is the worst for absorbing infrared radiation
What is white?
