[Access control system for a radioisotope laboratory with a personal computer]

Area of Science:

• Radiological Safety
• Laboratory Security Systems
• Access Control Technology

Context:

• Radioisotope laboratories require stringent security measures to prevent unauthorized access and the release of radioactive materials.
• Existing security systems may not adequately address the unique challenges of monitoring personnel and material flow in high-risk environments.
• The integration of multiple electronic components offers a potential solution for enhanced laboratory safety.

Purpose:

• To describe the design and implementation of an integrated access control system for a radioisotope laboratory.
• To detail the components and functionalities of the proposed security system.
• To evaluate the system's effectiveness in preventing unauthorized entry and material egress.

Summary:

• The described system utilizes a personal computer to control an electric door, card readers, a hand-foot cloth monitor, and a thermo sensor.
• User identification cards are processed to log gate number, user ID, and time, with data printed for record-keeping.
• A video tape recorder (VTR) linked to the sensor captures individuals passing through the gate, deterring unauthorized access and material release.

Impact:

• The implemented system effectively prevents the intrusion of unregistered individuals into the radioisotope laboratory.
• It successfully mitigates the risk of contaminated materials being released from the controlled area.
• This technological solution enhances overall laboratory safety and security protocols.
