. 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
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.
- To understand how gamma radiation is absorbed and attenuated by matter
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.

- How to prepare for using this exercise (to be written)
- Notes on methods for analysing the data (to be written)
- 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.
