• The W-MON project goal is to establish an automatic control mechanism of the presence of radioactive material in conventional waste containers at CERN using a distributed network of interconnected low-power radiation sensors. This network facilitates continuous data recording, transfer and storage in a database while allowing online and offline data analysis, in addition to alarm triggering. Data transmission, processing and evaluation is achieved by a centralized IoT end-to-end data architecture that has been developed for real-time monitoring and visualization of the radiation levels in waste containers. In this paper the results of field tests of the W-MON system described in two previous papers are presented for three different types of sensors. Estimation of failure detection probability, long-term stability tests and sensitivity studies carried out using radioactive samples of various activities placed in standard waste containers are described. A comparison between the manual monitoring procedure currently used at CERN and the W-MON system is discussed in detail. •W-MON system is a network of low-power radiation sensors.•Automatic control of radioactive material in waste containers at CERN.•Centralized IoT architecture enables continuous data transmission.•Real-time monitoring and visualization of radiation levels.•Long-term stability tests using radioactive samples in standard containers.•W-MON system can efficiently replace existing manual monitoring procedures.
