"The only good thing that came of it was that it washed a lot of the residual radiation into the sea," says Tanaka.
A lot of the dangerous radiation from the Sun and other outer space sources comes in the form of protons, which are relatively heavy and have trouble piercing even a thin atmosphere.
But if highly reflective clouds dominate the dayside of the exoplanet, they will block a lot of infrared radiation from the surface, said Yang, a postdoctoral scientist in geophysical sciences.
For one, Earth has a strong magnetic field, which deflects a lot of radiation (in the form of electrons and protons) from the Sun; Mars doesn't have that protection.
"They say there's still a lot of radiation in the soil, and that this gets into the food chain when cows eat the grass".' Local authorities say leukemia is a major problem among cows, and the animals have been placed under vigilant veterinary control.
Beyond Geiger counters, the group considered other opportunities for environmental monitoring and recognized that air quality reporting "suffered from a lot of the same problems as radiation," Mr. Bonner said.
There is a lot of radiation in the Fort, so beware.
"Something like Caesium 137, a product of nuclear reactors, has a half-life of 30 years and puts out a lot of gamma radiation, so is one of the more problematic isotopes.
In recent years, researchers have explored a lot of radiation protection approach, and some radiation protection approach have been applied in practice, such as visualization technique of radiation environment, path-planning method, robotics and etc., in these techniques the path-planning in radiation environment technology has become an important radiation protection measure.
