The Compton Effect illustrates the particle nature of gamma radiation. When a gamma quantum bounces off an electron, its energy loss depends on the scattering angle.
This kit consists of two pairs of shell-shaped targets and a central holder with adjustment screws and lead absorber. These rotationally symmetrical aluminum targets give a high count-rate for the two fixed scattering angles (approximately 60° and 90°).
With our gamma spectrometer and a standard Cs-137 source, viable difference spectra for both angles can be obtained within an hour. A lead absorber blocks the direct radiation from the source to the detector. Correction for background radiation (including scattered radiation from the table top, etc.) is handled by the included spectrometer software.
This product can expose you to chemicals including LEAD, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, see www.P65Warnings.ca.gov.
