INTRODUCTION (°) In this report are summarized the results of the measure• ments of environmental radioactivity performed by the site survey group of the Protection Service. The personnel of this group, which is super• vised by Prof. A. Malvicini, chief of the Protection Service, is the fol• lowing: responsible for Site and Meteorology Section: P. Gaglione responsible for the chemical laboratory: M. de Bortoli radioactivity measurements: O. Malgarini, E. Lovati chemical laboratory: E. Pecchio, L. Tortora, O. Cadario air monitoring stations: M. Tramontana sampling: G. Brughera, L. Pasqualini secretary: A. Schieppati The work is carried out in a chemical laboratory and in a radioactivity measurements laboratory, equipped for gamma and alpha spectrometry and low-level beta counting. The following reports on the same subject have already been published: CNI - 43 Misure di radioattività ambientale, Ispra 1958 - 59 CNI - 95 Misure di radioattività ambientale, Ispra I960 EUR - 223i Misure di radioattività ambientale, Ispra 1961 EUR - 48 li Misure di radioattività ambientale, Ispra 1962 EUR - 2213e Environmental radioactivity, Ispra 1963 EUR - 2509e Environmental radioactivity, Ispra 1964 Main object of the measurements performed is the constant knowledge of the radioactivity levels in the environment of the Euratom Ispra Establishment, in order to identify and evaluate radioactive conta• minations caused by the Establishment itself. (°) Manuscript received on April 12, I966 The results obtained from the surveillance program indica• te that, also for the calendar year 1965, the environmental radiation ex• posure for the persons living in the neighbourhood of the Establishment was due, almost exclusively, to natural sources and world-wide fallout. During I965 improvement of the radiological monitoring program has materialized in the following realisations: i) completion of the telemetering network for air radioactivi- ty; ii) adaptation and equipment of a vehicle as "mobile station". This unit, in radio communication with the central labora• tory, is foreseen to begin its activity early in 1966. The equipment is conceived for measurements of the gamma
