Absorption of radiation in matter (UiO)
RoboLab exercise developed at University of Oslo
Booking
To book a time slot for using this remote controlled laboratory you must contact Jon Petter Omtvedt (UiO): j.p.omtvedt[at]uio.no. Please provide full name, affiliation and when you would like to run the exercise. You will not be able to use the system before an made an appointment, you will then obtain necessary links and instructions for performing the exercise. Normally appointments are only done with teaching institutions and not directly with students.
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.
