With respect to levels of radiation, which of the following is most supported by the information in the article?

Scientists still have no information on how short-term exposure and long-term exposure to high levels of radiation affect living things.

Scientists now believe that climate plays an important role in determining how animals react to long-term exposure to high levels of radiation.

In studying the effects of high levels of radiation, Timothy Mousseau and his colleagues spent more time in the Fukushima region than they did in the Chernobyl region.

In July 2011, Timothy Mousseau and his colleagues went to the Fukushima and Chernobyl regions to discover why radiation levels were so high in both places.

Occasional brief exposure to a radiation level of 0.05 microsieverts is probably not harmful to most humans.
