We report the results of actual environmental radiation visualization at medical facilities using a portable high-sensitivity omnidirectional Compton camera with rotation function, which was reported at the conference in March. A revise of the online data collection method was carried out to facilitate the measurement. With this improvement, it became possible to acquire data while continuously rotating at constant velocity of 360 degrees in 1 minute, to check the measurement data during measurement, and, to determine the measurement period on site.
