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. Any point source which spreads its influence equally in all directions without a limit to its range will obey the inverse square law.

Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. If you took background CPM reading and subtracted them from every distance reading do you think the red line would cross closer to zero? The GM counter will not register those particles that pass through it in the dead time. Nuclear radiation is ionizing radiation. % After the source has been in storage for a year or so, it will become too weak to perform useful experiments. We classify this ionizing radiation into three major categories; gamma rays, beta and alpha particles. Using the coaxial cable with SHV plugs, connect the high voltage OUTPUT on the rear panel of the 556 High Voltage Power Supply to the SHV connector labeled "HIGH VOLTAGE" on the GM Pulse Inverter box. As the source is sealed there might be an error associated as to locating the precise position of the source so a greater distance between the source and the detector will reduce the error produced by not knowing precisely where the source is located. The law states that the intensity of radiation is inversely proportional to the square of the distance from the source. The first source we will use is the polonium-210 alpha particle source.
