WRITING COLLATOR FOR DUST COLLECTION REQUIREMENT

摘要

PURPOSE:To achieve a highly accurate radiation management by collating a dust collection requirement information for the writing with a magnetic recording written into a dust collection filter paper loaded into a dust collector of a radioactive dust monitor to determine the adequateness thereof. CONSTITUTION:A dust collection requirement of a dust collector is written magnetically into a filter paper 16 with a head 42 through a control section 40 or the like with a CPU, a ROM and a RAM and the like in response to an operation panel 12. Upon the end of the writing, the operation is automatically shifted to the collation mode which is indicated on a display 14 while a magnetic record on a paper 16 is read with the head 42 as moving through a card through 18 by way of the control section 40 and a feeding mechanism section 44 and collated with dust collection requirement information for writing memorized while it stays in the control section 40 to determine the adequateness thereof. When it is not proper, an alarm is issued and a correct dust collection requirement is always written into the filter paper to achieve a highly accurate radiation management.
