Ionizing radiation and plant growthFeatured science projectScience project video

Conclusion

The hypothesis that overexposure to  X-rays  causes tissue damage and prevent the green beans from germinating, is proven to be true.

Ionizing radiation is often used in medical applications such as radiation therapy. It is also used to sterilize tools and equipment in industrial applications. Irradiation is the process of sterilizing food with a lower dosage of radiation. The amount of radiation used is enough to kill the microbes but not enough to make food more radioactive.

Also consider

This science fair project can also be repeated to see if other plant seeds like tomato, chili or sunflower exposed to X-ray ray will germinate.

Try and repeat this science fair project by using  radiation from an ultraviolet lamp.
