主　　题：Atmosphere radon gas gamma radiation. 

摘      要：It is common knowledge that we live in an environment which comprises ionizing radiation （X-rays, gamma rays）. These radiation in normal situations is produced by natural phenomena such as cosmic rays from different sources in Universe and the decay of radioactive elements present in the Earth planet atmosphere and crust. Ionizing radiation can also be produced by human activities such as those related to nuclear power generation and use in medicine and industry. Although ionizing radiations are part of our daily lives, few students or researchers have the opportunity to perform measurements and observations of the background radiation. To overcome this deficiency in education, we started a pilot project that propose measures and observations of environmental radiation background with students of the ITA （Technological Institute of Aeronautics, Silo Paulo）. Using compact and portable detector to observe gamma radiation like described in this work, many graduate students can participate.
