Answer 1

11. Reproductive cells are more radiosensitive, whereas nerve cells are less radiosensitive.

Amongst the body cells, the most sensitive are spermatogonia and erythroblasts, epidermal stem cells, gastrointestinal stem cells. The least sensitive are nerve cells and muscle fibers.

12. Three principal advantages of the use of charge coupled devices in fluoroscopic digital imaging are distortion free images, unaffected by external magnetic fields and constant image quality over the entire image.

13. Following the Chernobyl reactor accident what fission product isotope was released that is a cause for thyroid cancer, particularly in children? ¹³¹I – an isotope of iodine

14. Radiation exposure occur in indoor air and in uranium mining in some parts of the US principally from what relatively common, gaseous radioisotope?

Answer is: Radon

15. The first general purpose electronic computer system was established in 1987 at the Univ of pennsylvania and was called Electronic Numerical Integrator and Computer (ENIAC)
