Ionizing radiation comes from these main sources:
Nuclear reactions in the Earth's sun and stars in space.
Radioactive decay in the body's tissues and in the soil.
Radioactive decay of unstable elements in rocks, especially rocks that contain radium and release radon gas.
Other examples of ionizing radiation include alpha, beta, and gamma rays from radioactive decay.
It is a beneficial adaptation since the pressurized seeds and spores spread widely, helping the organism reproduce elsewhere. In plants, it allows them to survive better by flinging the seeds far away so that their offspring don’t compete for food. For the fungus, it allows the parent to fling the spores into the grass so that when other animals eat them, the life cycle of the fungus continues on. These may be dispersed by the wind.
