Putting radiation to use This is a product of Mr Essex a member of the science department of Dartford Technology College

Question 1 There are three types of nuclear radiation; Alpha, Gamma and ? Zeta Omega Delta Beta

Question 2 Alpha radiation is a particle consisting of two neutrons and two protons it can best be describe as a nucleus of ? Hydrogen Helium Lithium Beryllium

Question 3 Beta particles are much smaller than Alpha particles and much faster. They are essentially a sub atomic particle called ? Proton Neutron Electron Nucleus

Question 4 Gamma rays are not particles at all they are part of ? Visible light Radio waves Micro waves Electromagnetic spectrum

Question 5 What is the charge of an Alpha particle ? 1 minus 2 minus 1 plus 2 plus

Question 6 What is the charge on a Beta particle ? 1 plus 2 plus 1 minus 2 minus

Question 7 Americium 241 is found in household smoke detectors it gives off a constant stream of ? Alpha particles Beta particles Gamma rays Microwaves

Question 8 What is an Ion ? Something that has lost or gained a nucleus.Something that has lost or gained a nucleus. Something that has lost or gained an electron.Something that has lost or gained an electron. Something that has lost its way.Something that has lost its way Something that has lost or gained weight.

Question 9 We measure the amount of radiation with a GM tube and counter. What does GM stand for ? Geiger Muller Geiger Mitchell Gregory Muller Gregory Mitchell

Question 10 The Geiger Muller tube can also detect natural background radiation from cosmic rays and ? Hydrogen gas Radon gas Radium gas Uranium gas

Question 11 The GM tube gives a result in CPM this stands for ? Counts per million Counts per microgram Counts per minute Counts per month

Question 12 Which type of radiation can be stopped by a few centimetres of air or a few sheets of paper? Alpha Beta Gamma Delta

Question 13 Which type of radiation can be stopped by a few centimetres of aluminium ? Delta Gamma Beta Omega

Question 14 It would take very thick lead sheets and many metres of concrete to stop ? Alpha particles Beta particles Gamma rays Delta rays

Question 15 Which type of radiation would be best to detect underground leaks? Alpha Beta Gamma Delta

Question 16 What are X-rays used for in hospitals ? To mend broken bones.To mend broken bones To find broken bones.To find broken bones To mend muscles. To find torn muscles.

Question 17 Isotopes of Hydrogen have different numbers of ? Protons Electrons Nucleus Neutrons
