_Imagine Dragons - Radioactive | Acoustic Cover
"imagine dragons" radioactive cover - Radioactive materials in wide use within the United States could be changed into capons of terror that would probably kill few individuals but would spread panic id produce severe economic damage, scientists told the Senate Foreign stations Committee today.

The materials wouldn't produce nuclear explosions. Rather, they'd spread using conventional explosives in so-called dirty bombs. The scientists up testified at the committee's hearing today said such weapons were a textually major problem.
One of the most dangerous materials, i was told that, are bars radioactive cobalt (IS) used to irradiate food, medical devices as well as other products to sterilize ( $j if ) them.
If turned into fine particles dispersed underneath the right conditions, the cobalt could spread en radiation to force the abandonment of the area the dimensions of Manhattan, the scientists said. But federal and industry officials said this kind of action by using it.
radioactive cobalt was unlikely as a result of intense radiation that thi person attempting to make use of the weapon will be exposed and since the fabric ii transported in secret and kept behind a lot of lead along with other shielding while o$ the path or in use.
Other radioactive materials in tens of thousands of medical and industrial devices might be accustomed to make weapons that will leave wide areas will radiation levels above Epa limits, possibly leaden| to temporary evacuation and an extremely difficult cleanup.
Scientists at this hearing held to understand these threats and to devise methods for protecting Americans against them asserted they remained concerned that fissionable material - the fuel for nuclear weapons - and also the expertise required to use it could be spreading from the former Soviet Union to terrorist networks, but presented no new evidence of such leakage.
Dr. Richard Me serve, chairman of the Nuclear Regulatory Commission said that these materials, as well as the much more powerful cobalt rods used in sterilizing food, are tightly controlled. He said the weaker sources, i dispersed, would cause almost immeasurably small increases in cancer rate among individuals who were exposed.
Nevertheless, that kind of attack might cause long-term problems because methods for working with radioactive contamination rely largely on destruction and removal, Dr. Henry Kelly president from the Federation of yank Scientists, said.
Because limits set b the Environmental Protection Agency for radiation exposure are so low, are? Might have to be evacuated for a long time even when the health risks air relatively slight, he was quoted saying. Nave cooled slightly in the past few years.
That's been puzzling, because :he polar regions are usually more sensitive to warming trends than the -east from the globe. Much more puzzling, a small portion of Antarctica - the peninsula that stretches north toward South America - defies the cooling rend. It has been warming very quickly, about five degrees within the last 50 'ears, 10 times the world average.
Writing in the current publication of the journal Science, Dr. David Thompson, a professor of atmospheric science at Colorado State University, and Dr. Susan bloom, a senior scientist at the National Oceanic and Atmospheric administration in Boulder, Colo., argue that the ozone hole, which has penned up each spring over Antarctica in recent years, might help explain both introductory trends.
