“Hands on Training on G.M. Counters”

Hands-on Training Session on the GM Counter

The hands-on training session on the GM Counter (Geiger-Muller Counter) was conducted by Prof. Manohar Lal Kaushal at the nuclear physics lab of G.G.D.S.D College Hariana. The training aimed to provide students with practical knowledge and skills in radiation detection and measurement using this essential device.

Introduction to the GM Counter

The GM Counter is a critical instrument used to measure ionizing radiation, widely applied in fields such as nuclear physics, environmental monitoring, and medical diagnostics. The primary objective of the training was to familiarize students with the operation and principles of radiation detection and measurement.

Training Highlights

• Students were introduced to the basic structure and function of the GM Counter by Prof. Kaushal. He explained how the device detects ionizing radiation using the ionization effect produced by radiation passing through a gas-filled tube.
• Prof. Kaushal demonstrated how to set up and calibrate the GM Counter, including assembling the GM Counter unit, connecting it to the power source, and setting the sensitivity levels based on the type of radiation being detected.
• Each student was given a GM Counter to measure radiation levels from various controlled sources (e.g., alpha, beta, and gamma emitters). The training focused on identifying the radiation source, recording the count rate (measured in counts per second or minute), and differentiating between background radiation and radiation from sources.
• Students were instructed on how to interpret the results obtained during the training. This included calculating radiation dose rates and understanding the implications of the data in terms of safety and environmental conditions.

Student Outcomes

All students demonstrated competence in setting up and using the GM Counter to detect and measure radiation. They appreciated the practical approach and the clarity of Prof. Kaushal's instructions. The training was a success, providing students with practical experience and increased confidence in using the device for radiation detection and measurement.

Conclusion

Hands-on training transforms passive learning into an active and immersive experience, making it an effective educational tool. This session equipped students with the knowledge and skills they need for success in fields related to radiation detection and measurement.
