Robolab Exercise - Absorption and Detection of Gamma-Radiation
Run the Exercise
To run this exercise click here: http://kj-robolab3.uio.no:8000/RoboLab.html. Before you can run the exercise you need to have booked a time slot (see below) and have installed the appropriate LabView plug-in (as explained on the main RoboLab page).
Booking
To book a time slot for using this remote controlled laboratory you must contact Jon Petter Omtvedt (UiO). Please provide full name, affiliation and when you would like to run the exercise. You will not be able to use the system before you have received a username and password.
Learning Goals
To understand how gamma radiation is absorbed and attenuated by matter
Introduction
In this exercise, you use RoboLab to measure the radiation of a γ source with a NaI detector. Absorbers of different materials and varying thickness are placed between the source and the detector to demonstrate how the gamma ray intensity is attenuated by the shielding.

Alternative uses
This RoboLab setup can be used to investigate counting statistics and standard deviation related to measurement of radiation. Attenuate the count rate by selecting a suitable lead absorber thickness and have the students perform measurement series under identical conditions to observe the deviation in the number of counts.
