![]() |
![]() |
Code Number: 7D10.20
Demo Title: Half Life - Isotope Generator
Condition: Excellent
Principle: Natural and Artificial Radioactive Sources
Area of Study: Modern Physics
Equipment:
Nucleus counter and tube, isotope generator and kit, eluting solution.
Procedure:
Force about 1 ml of the eluting solution through the generator and collect 7 or 8 drops of the passed solution in one of the planchets. Immediately place disk in the tube holder and start the counter. Counting will be done for 10 thirty-second intervals for a total of 5 minutes. The half life of Barium 137M is 2.55 minutes (2 min, 33 sec). With a 661.6 keV gamma ray being emitted.
NOTE: Background count should be determined before sample counting begins.
