Abstract

PURPOSE:To detect the charging state of concrete with good measurement accuracy by adjusting a radiation source which is arranged in front of a form and enters a neutron ray into a concrete deposited area and a detector which is arranged in front of the form and detects the neutron ray reflected by the concrete deposited area with good measurement accuracy. CONSTITUTION:The state wherein concrete C is charged in the concrete deposited area 3 is viewed and then the radiation detector 6 of a detecting device 4 provided in front of the form 2 is moved sideward and position-adjusted to find a position where the neutron ray R which is incident on and reflected by the concrete C charged in the concrete deposited area 3 from a radiation source 5 with good sensitivity. Then the detecting device 4 is arranged in front of the form 2 at the position where the charging state of the concrete C is to be detected so that the position P relation between the radiation source 5 and radiation detector 6 is the relative position relation with the best sensitivity to the neutral ray R, thereby confirming whether or not the concrete C is securely charged in a desired area 3.
