Radiation Flashcards
(17 cards)
What is nuclei
It is the central core of something
what is nuclear radiation
It is radtion from the nucleus of the atom
What are the 3 types of radiation
Alpha, Beta, and Gamma
Which one is the strongest
Gamma,Alpha or Beta
Gamma
what is background radition
It is raditon from radicotive substances occuring naturally
Is Background radition bad for us
No it is harmless
what is ionising radiation
Ionising radiation is energy (or particles) that travels through space or matter. It is a type of radition with enough atoms to remove electrons from atoms and make them charged
why are Alpha, beta and gamma radiation are all forms of ionising radiation
because of their ability to pull electrons from nearby atoms and molecules, turning them into ions.
what are some long term effects of exposure to small amounts of radition
can cause DNA damage, cancer and tumour growth
what are some short term effects of exposure to large amounts of radition
can cause burns, nausea, destruction of bone marrow and blood cells, and death.
what type of radtion is A radioactive particle that has the same size and mass as an electron
Beta particle
what type of radtion is A radioactive particle that is made up of two protons and two neutrons
Alpha particle
What type of radition is The type of radiation that can penetrate the human body and can be stopped only by a thick shield of lead or concrete
Gamma Particle
A radioactive particle that can travel almost at the speed of light is what kind of radition
Beta Particle
A radioactive particle that carries the highest amount of charge is what kind of radition?
Alpha particle
Radiation which has the smallest penetrating power
Alpha particle
Radiation that travels as a wave rather than a particle
Gamma radiation
