Cosmic rays, Ultraviolet, Yeast, Seeds, Weather balloon


Cosmic and ultraviolet rays are pervasive and often difficult to avoid, for atmospheric pollution has caused an increase in harmful radiation reaching the Earth's surface due to the rapid depletion of the ozone layer. Because the deterioration of the ozone layer is a recent phenomenon, it is important to understand the rays’ effects on the DNA of organisms. It is also an area of interest in the field of astrobiology as humans begin to consider the possibility of long-term exposure of crops to these types of radiation in prolonged space travel. The Bioballoon project, described in this paper, was a payload for a weather balloon built to expose samples of yeast and seeds to cosmic and ultraviolet rays in the middle to upper stratosphere. After plating the yeast and planting the seeds, it was found that although cosmic and UV radiation appeared to induce mutations in yeast genes, they do not produce significant phenotypic differences in plants.
