Resumo
Neutron Activation Analysis (NAA) is a well-established nondestructive analytic technique where the gamma
radiation emitted by an irradiated sample is analyzed using an HPGe detector. The Neutron Activation
Laboratory (LAN) of IPEN-CNEN/SP has been performing NAA analyses for over 30 years, and has plans of
implementing quality control protocols to their analyses. In this sense, the environmental monitoring of the
laboratories where the detectors are used has been performed for many years, in a manual way with no more
than 2 measurements per day. In this work, an automated monitoring station based on a microcontroller Arduino
UNO board has been developed which comprises four thermo hygrometer sensors for monitoring different parts
of the environment, plus a thermocouple for monitoring the inside of the liquid nitrogen dewar. The results
obtained allow for a discussion on the performance and adequacy of the sensors.
