Prototype portal monitor characterization using source Cs¹³⁷

Initial testing has been conducted on the prototype portal monitors using Cs¹³⁷ source type 250 milli Curie. These tests include testing of the remote control system through the internet and the data acquisition system on a prototype portal monitors. The purpose of testing is to determine the performance of the control and data acquisition system to obtain the expected image. The test results show that the control system of portal monitors can be operated and controlled through the internet. The test results show that the data acquisition system acquisition system can produce 2-dimensional image although not satisfactory, this is caused by the possibility of a small source activity. On further research will be tested using a larger source of Cs¹³⁷ 500 milli-Curie. (author)
