PURPOSE:To input work information quickly in safety to a dosimeter by linking a pocket dosimeter equipped with an alarm and a work information input means through radio communication function and disposing a dosimeter closely to the antenna of the work information input means. CONSTITUTION:A work information input means transmits transmission request signals periodically from an antenna at a constant time interval. A pocket dosimeter with alarm receives radio wave from the antenna 2 at a radio communication section and sends back an acknowledgement signal when a microcomputor ackowledges the transmission request signal. When the communication is established, a relevant work data is read out from a document by means of a bar code reader 9 and communicated. If an error occurs in the way, a message is presented on the display of the dosimeter and on the display 10 of the input means and an alarm is sounded. This constitution eliminates the need of taking out the dosimeter from the working jacket and allows noncontact input of work information to the dosimeter for the worker. |
