The percent growth for radish seedlings are 100% for the control, 90% for 50,000 rads, 96% for 150,000 rads, 76% for 500,000 rads, and 0% for four million rads. The control was the most successful at germinating since it had no radiation, followed by the seeds exposed to 150,000 rads, 50,000 rads, 500,000 rads, and four million rads, whose seeds did not germinate. The root lengths for radish seedlings are 78 millimeters for the control, 46 millimeters for 50,000 rads, 46 millimeters for 150,000 rads, 14 millimeters for 500,000 rads, and 0 millimeters for four million rads. The control had the most successful height since it had no radiation, followed by the seeds exposed to 50,000 rads, 150,000 rads, 500,000 rads, and four million rads, whose
