TRANSPORT PORTAL RADIATION MONITOR Russian patent published in 2009 - IPC G01T1/167 

FIELD: physics, measurement.

SUBSTANCE: invention is related to the field of environment protection, and more precisely, to facilities of radiation-hazardous substances registration in process of their transportation through monitor in transport means. Substance of invention consists in the fact that monitor is made in the form of premise of hangar type closed by automatic gates, in concrete floor of which evenly along its whole length, grooves are arranged. In these grooves the first detectors 1 are installed (floor), and the second detectors 2 are installed on two beams mounted on both sides along ceiling part of closed premises, closing zones of lowered sensitivity of floor detectors 1. Grooves with detectors 1 in floor part of premises are closed aflush by protective plugs, and electric cables from detectors, gates and traffic lights are taken out of the limits of closed premise for transport vehicle into operator's room, where monitor control panel is installed.

EFFECT: higher sensitivity of control due to maximum proximity of detectors to transport vehicle.
