Yes, you can use an outdoor plant box to grow plants that serve as natural neutron absorbers. Certain plants, such as sunflowers, mustard greens, and water hyacinths, have been studied for their ability to absorb neutrons and other forms of radiation. These plants can be cultivated in outdoor plant boxes, making them a practical and eco-friendly solution for radiation protection in residential or small-scale environments.

To maximize effectiveness, choose plants with high biomass and dense foliage, as they tend to absorb more neutrons. Ensure your outdoor plant box is placed in a sunny location and filled with nutrient-rich soil to promote healthy growth. Regular watering and maintenance are essential to keep the plants thriving.

While these plants won’t replace industrial radiation shielding, they offer a supplementary layer of protection and contribute to a greener environment. Combining gardening with radiation mitigation is an innovative approach worth exploring for hobbyists and eco-conscious individuals alike.
