License exempt radioactive isotope button sources are available for purchase. A GM tube usually consists of an airtight metal cylinder closed at both ends and filled with a gas that is easily ionized (usually neon, argon, and halogen).

Efficiency of GM counter for various sources b. The intensity of radio waves over distance obeys the inverse-square law, which states that intensity is inversely proportional to the square of the distance from a source. The "inverse square law" applies to geometric dilution of radiation around a source in the limits of point approximations for the source and detector, negligible material attenuation between source and detector, and no scattering. Sometimes these approximations are good, sometimes they are not. I placed this source 3 cm from the front of the GM tube. If you want subjects to be evenly lit from one side to the other, crank up the power and make the distance of the flash no less than the width of your subject . ?{SnTh/*83T?Ze(IX^a8:"T|fU4S}^>V|%oKa*BR_5h|jxu4Bzbr}a IU9Y(t,s)B=KFgjs@4|N+aNdf9$gF\S3=")T|{|U~MI]?X]l$E3`y6"-44cI 722 722 722 722 722 722 889 667 611 611 611 611 333 333 333 333 1.2.3 Determining Uncertainties from Graphs, 2.2.7 Collaborative Efforts in Particle Physics, 2.3 Conservation Laws & Particle Interactions, 2.4.2 Threshold Frequency & Work Function, 3.2.4 Required Practical: Investigating Stationary Waves, 3.3.4 Developing Theories of EM Radiation, 3.3.5 Required Practical: Young's Slit Experiment & Diffraction Gratings, 4.3.7 Required Practical: Determination of g, 4.6.2 Area Under a Force-Displacement Graph, 4.6.5 Kinetic & Gravitational Potential Energy, 4.8.2 Required Practical: The Young Modulus, 5.2.4 Required Practical: Investigating Resistivity, 5.4 Electromotive Force & Internal Resistance, 5.4.1 Electromotive Force & Internal Resistance, 5.4.2 Required Practical: Investigating EMF & Internal Resistance, 6.2.1 Conditions for Simple Harmonic Motion, 6.2.3 Calculating Maximum Speed & Acceleration, 6.2.8 Required Practical: Investigating SHM, 6.5.5 Avogadro, Molar Gas & Boltzmann Constant, 6.5.6 Required Practical: Investigating Gas Laws, 7.1.5 Gravitational Field Strength in a Radial Field, 7.2.2 Calculating Gravitational Potential, 7.2.3 Graphical Representation of Gravitational Potential, 7.3.1 Circular Orbits in Gravitational Fields, 7.4.7 Comparing Gravitational & Electrostatic Forces, 7.5.2 Graphical Representation of Electric Potential, 7.7.4 Required Practical: Charging & Discharging Capacitors, 7.8.1 Magnetic Force on a Current-Carrying Conductor, 7.8.6 Required Practical: Investigating Magnetic Fields in Wires, 7.9.3 Principles of Electromagnetic Induction, 7.9.6 Required Practical: Investigating Flux Linkage on a Search Coil, 8.1.4 Inverse-Square Law of Gamma Radiation, Measure the background radiation using a Geiger Muller tube without the gamma source in the room, take several readings and find an average, Next, put the gamma source at a set starting distance (e.g. 600 600 600 600 600 600 600 600 600 600 600 600 600 600 600 600 [ It only takes a minute to sign up.
