| Popis: | Effects of ionizing radiation on the emergence of locomotor skill, and physical development were studied in laboratory rats (Fisher F-344 inbred strain). Rats were treated with 3 different doses of radiation (150 rad, 15 rad, and 6.8 rad) delivered on the 20th day of prenatal life. Results indicated that relatively moderate (15 rad) to high (150 rad) doses of radiation had effects on certain locomotion and physical development parameters. Exposure to 150 rad delayed pivoting, cliff-avoidance, upper jaw tooth eruption, and decreased body weights. Other parameters, such as negative geotaxis, eye opening, and lower jaw tooth eruption were marginally delayed in the 150 rad treated animals. Exposure to 15 rad delayed pivoting and cliff-avoidance. |
