title: [Access control system for a radioisotope laboratory with a personal computer].
abstract: This paper describes an access control system for a radioisotope laboratory. The system is composed of a personal computer, three card readers, an electric auto door, a hand foot cloth monitor, a monitor TV, a video tape recorder (VTR), and a thermo sensor. The personal computer controls other equipment with a registered user's number. When a user inserts an identification card into the card reader, the computer stores the gate number, the user's number and the time; it processes those data and prints out a document. The VTR records the person passing through the gate to identify if he uses his card. It works only when the sensor catches users being within its sensitive area. This system proved to effectively prevent intrusion into the area of an unregistered person or release of contaminated materials from that area.
