ABSTRACT
Humans are exposed to the nuclear radiation in the environment which can be very harmful to their health. Radioactive detectors used in detecting this are expensive, fixed and have poor portability. To address this problem, this study aims to develop a portable mobile nuclear radiation detector. The detector node will be constructed with the use of a microcontroller, a Geiger counter, and a GSM/GPRS shield, which will then be mounted on a Lego Mindstorms robot. The data collected by the detector will be measured in micro Sieverts and will be transmitted through the GSM shield to the Smartphone app through the GSM/GPRS network. However, conflict between the pins used by radiation shield and GSM/GPRS shield has disabled the function of sending the data to android phone, and the reading of radiation. Individually, it can function well. It requires splitting the signals in order to completely function. In conclusion, a lightweight nuclear detector was developed though it could not send the data to the smartphone application.
