1) Individual particles in cosmic radiation have extremely high energy, which implies that they are potentially damaging.

2) One or two meters of rock will block cosmic radiation.

3) Background cosmic radiation levels in free space are ten times greater than the maximum acceptable levels for individuals who work in radiation environments on Earth.

4) It will also gather information from cosmic radiation sources on stars and galaxies millions of light years away.

5) Cosmic radiation impact varies according to air routes, reaching its maximum at two poles.

6) The telescopes sift through the background cosmic radiation to find spots where it has been slightly perturbed as it passes through extremely hot gas, a hallmark characteristic of galaxy clusters.

7) After being exposed to cosmic radiation and zero gravity, some seeds may mutate and produce higher yields and improved quality when planted back on earth, scientists said.

8) Objective To estimation cosmic radiation effective dose, to which the flight personnel of different types of work of airline was exposed.

9) If they happen to hit the earth, the cosmic radiation dose may be significantly increased for a short period from hours to a few days.

10) Objective To calculate individual annual cosmic radiation effective dose for monitored flight personnel.

11) The primary cosmic radiation that reaches the earth is minimum at periods of maximum solar activity.

12) Objective To study a simple method for estimating cosmic radiation effective dose rate for aircrew.

13) Objective To study the influence of cosmic radiation on the lymphocyte micronucleus of civil aviation pilots and crew members.

14) The doctors suspected that his ability to absorb ascorbic acid had been impaired by long exposure to cosmic radiation.

15) The cytokinesis-blocked micronucleus method is sensitive to represant the difference in flying load, therefore, it could be used to monitor the damage induced by cosmic radiation.

16) Chinese government, in 2002,[http:///cosmic radiation.html] promulgated and implemented the standards for controlling exposure to cosmic radiation of air crew GBZ 140—2002.

17) We use the rare isotope Beryllium-10, which develops in the land surface via cosmic radiation.

18) Bothe: German physicist . He shared a 1954 Nobel Prize for his research on cosmic radiation.

19) Thermoluminescence studies of meteorites suggest that the level of natural TL in meteorites is determined by competition between build up, due to exposure to cosmic radiation, and thermal decay.

20) According to a statement, the new neutron beam line will replicate the cosmic radiation affecting microchips from 100 years of flying time in the space of an hour.

21) Objective To evaluate the altitude and latitude dependence of neutron dose of cosmic radiation encountered by aircrew of international airlines.

22) Chinese scientists claim to have created a range of so-called super crops by blasting seeds into space so their genes are mutated by cosmic radiation.

23) Along the way the astronauts would be bombarded by cosmic radiation and risk being baked by unpredictable solar flares.

24) The field may therefore be old enough to have shielded some of the planet’s earliest life from the sun’s most harmful cosmic radiation.
