<P>PROBLEM TO BE SOLVED: To provide a radiation measurement device and a radiation measurement method that can measure a spatial distribution of dosages of radiation from an object to be measured. <P>SOLUTION: The radiation measurement device includes: ion detection means 18; blowing means 17; and arithmetic means 19 of calculating a radiation dosage distribution of an object to be measured 15 by using an air velocity ν, movement times t<SB POS="POST">1</SB>, ..., t<SB POS="POST">i</SB>, ..., t<SB POS="POST">n</SB>, current I, a conversion coefficient S and an equation (1) defining the relation among the air velocity ν of air blown to the side of the ion detection means, the times t<SB POS="POST">1</SB>, ..., t<SB POS="POST">i</SB>, ..., t<SB POS="POST">n</SB>that it takes for an ion 16, ionized with the radiation included in the air blown to the side of the ion detection means and emitted from the object to be measured 15, to move from respective meshes obtained by dividing the object to be measured 15 into n pieces to the ion detection means, the current I generated as the ion detection means detects the ion, and the conversion coefficient S for converting the current I into dosages R<SB POS="POST">1</SB>, ..., R<SB POS="POST">i</SB>, ..., R<SB POS="POST">n</SB>. <P>COPYRIGHT: (C)2013,JPO&INPIT |
