Creating a plant-based gamma ray telescope using outdoor plant boxes is an innovative and eco-friendly approach to amateur astronomy. While traditional gamma ray detectors rely on complex electronics, this method leverages the natural sensitivity of certain plants to radiation. Here's a step-by-step guide to building your own:

1. Select Radiation-Sensitive Plants: Choose species like sunflowers or ferns, which are known to respond to gamma radiation. Plant them in sturdy outdoor boxes with nutrient-rich soil.

2. Install a Shielding Frame: Construct a lightweight wooden or PVC frame around the plant box to block background radiation. Line it with lead sheets or aluminum foil for added protection.

3. Add a Photographic Plate: Place a high-sensitivity photographic film or plate near the plants to capture gamma ray interactions. Secure it in a lightproof casing.

4. Monitor Plant Health: Observe changes in plant growth, leaf discoloration, or other biological responses that may indicate gamma ray exposure.

5. Analyze Results: After weeks of observation, develop the photographic plate and compare plant health data to identify potential gamma ray sources.

This low-cost, sustainable method offers a creative way to explore gamma ray astronomy while connecting with nature. While less precise than professional equipment, it’s a fascinating project for science enthusiasts.
