摘要：PROBLEM TO BE SOLVED: To provide a radiation measurement device thatfeatures a minimized height of a detection unit having an ionization chamber, andairtightness of and a space secured for accommodating a plurality of electronic circuitboards in a lower space right below the ionization chamber.SOLUTION: A cylindricalsection 14 has a main space 24 having an ionization chamber 30 accommodated therein.Straight below the ionization chamber 30 is a lower space 26 formed as an airtight space,the lower space having a first circuit board 40 with an electrometer circuit disposedhorizontally therein. An adjacent space 28 is formed behind the lower space 26 with apartition wall 60A in between, the adjacent space being a non-airtight space having asecond circuit board 46 with power supply and other circuits vertically disposed therein.The partition wall 60A is provided with a sealing structure 78 for a plurality of signal linesto be inserted.SELECTED DRAWING: Figure 6
