The aim of this experiment is to verify the inverse square law for gamma radiation of a known gamma-emitting source, // endobj According to the inverse square law, when the distance is doubled from 8 cm to 16 cm the reading should decrease to 1/4 its initial reading. Recall that work equals force times, Emergency responders for radioactive material incidents normally use the inverse square law of radiation to estimate the separation distance from the radioactive source. No, because the wrist-watch glass is small and all the legs of the spherometer cannot rest on it. Hence this ndicates the verification of the equations derived and method devised. 333 444 500 444 500 444 333 500 500 278 278 500 278 778 500 500 The inverse-square law works as follows: If you double the distance between subject and light source, it illuminates a surface area four times greater than the one before.

Using forceps, a place a radium source 5 C on another stand and align it until its active face faces the tube window and lies along the axis of the tube. To verify the law plot the inverse of the square root of the intensity versus distance. The solutions to this differential equation include the Keplerian motions, as shown, but they also include motions where the orbit is a hyperbola or parabola or a straight line. To obtain, accuracy for this experiment, the distance between the source and the detector (GM, tube) needs to be several times greater than the diameter of the GM tube. Applications Of Inverse Square Law This law is used to calculate the intensity of any given radiation or distance. The absorption of the radiation by the air could explain the observed deviation from the inverse square law. 28.
