Mobile Low-Cost Spectrometer API [IN DEVELOPMENT]

The Mobile Low-Cost Spectrometer API is an accessible solution for measuring radioactivity and the energy of ionizing radiation, such as alpha particles and electrons. This system is based on two existing projects: the RadStar Alpha equipment and the DIY project supported by CERN (https://github.com/ozel/DIY_particle_detector/).

Overview

This compact spectrometer is designed to provide real-time data, enabling its use in fieldwork, educational applications, and scientific studies. With a portable and affordable design, it democratizes access to radiation measurement, making it an essential tool for a wide range of users.

Features

  • Radioactivity Measurement: Capable of detecting and measuring the energy of alpha particles and electrons.
  • Accessible API: Facilitates integration with other applications and platforms.
  • Compact Design: Ideal for field use and easy transport.
  • Real-Time Data: Enables instant monitoring and analysis.
  • Diverse Applications: Suitable for educational, scientific, and environmental safety contexts.

Technologies Used

  • Based on RadStar Alpha: Reference equipment for alpha radiation measurements.
  • DIY CERN Project: Incorporates concepts and technologies from the DIY low-cost spectrometer project supported by CERN.

Components Used

The table below lists the original components from the CERN project and their respective substitutions used in my project. This substitution aims to use more accessible components available in the local market while maintaining the original project's functionality.
