The safe storage and monitoring of radioactive materials are critical in ensuring the protection of individuals and the environment, particularly in educational and laboratory settings. Conventional storage systems that rely on mechanical locks and manual record-keeping are increasingly inadequate, as they lack real-time monitoring, automated access control, and immediate alert mechanisms. These limitations can lead to unauthorized access, incomplete usage records, and delayed detection of radiation hazards. Therefore, this project presents the development of a smart safety box integrated with Internet of Things (IoT) technology to enhance the security and monitoring of radioactive material storage.

The proposed system utilizes an ESP32 microcontroller as the central processing unit to manage multiple sensors and modules. A fingerprint sensor (AS608) is implemented to provide secure and reliable user authentication, ensuring that only authorized personnel can access the safety box. A solenoid lock mechanism is employed to physically secure the storage compartment, which is controlled electronically based on authentication results. Additionally, a PIR motion sensor and an ESP32-CAM module are integrated to detect movement and capture images of any unauthorized access attempts, providing an additional layer of surveillance.

To address radiation safety, a Geiger-Muller counter sensor is incorporated into the system to continuously monitor radiation levels inside the safety box. The system is capable of detecting abnormal radiation levels and triggering alerts when the measured values exceed predefined safety thresholds. An I2C LCD 1602 display is used to provide real-time information such as access status, radiation readings, and system notifications to users. Furthermore, the IoT capability of the ESP32 enables remote monitoring and notification, allowing users to receive real-time updates and alerts through an online platform.

This project aims to improve the overall safety, security, and efficiency of radioactive material storage by integrating access control, environmental monitoring, and automated data recording into a single system. The implementation of this smart safety box not only enhances protection against unauthorized access but also ensures continuous radiation monitoring and accurate usage tracking. As a result, the system contributes to a safer laboratory environment and demonstrates the potential of IoT-based solutions in biomedical and radiological applications.
