<p>PURPOSE:To obtain a survey meter which enables easy preparation of a dose equivalent rate map being effective for reduction of exposure. CONSTITUTION:A radiation detected by a radiation detector 1 is passed through an amplifier circuit 2 and a discriminator circuit 3 and outputted from a counter circuit 4, and it is converted by a one-chip microcomputer 5 into a dose equivalent rate (millisievert) which is a unit of the radiation. The data obtained by the conversion are displayed in a display unit 6 together with a measuring time, an operation area code (the number of an operation area) and an address (the number of a divided region in the operation area) and stored simultaneously in a removable memory card 7. These data are processed by the computer and a dose equivalent rate map is prepared.</p> |
