Normally, in the presence of radiation, communication links fail. But with autonomous robots, you don't need communications.
In America, we have always taken it as an article of faith that we 'battle' cancer; we attack it with knives, we poison it with chemotherapy or we blast it with radiation. If we are fortunate, we 'beat' the cancer. If not, we are posthumously praised for having 'succumbed after a long battle.'
I am a type-2 diabetic, and they took me off medication simply because I ate right and exercised. Diabetes is not like a cancer, where you go in for chemo and radiation. You can change a lot through a basic changing of habits.
The worst situation with radiation escaping is if you are downwind from it. You could virtually be on one side and not affected by the radiation. If you're on the other side and you're downwind from it, you are going to be affected.
Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.
There's almost no food that isn't genetically modified. Genetic modification is the basis of all evolution. Things change because our planet is subjected to a lot of radiation, which causes DNA damage, which gets repaired, but results in mutations, which create a ready mixture of plants that people can choose from to improve agriculture.
Radiation doesn't recognize borders. A meltdown in Japan or India, say, is a danger to the whole world. Wind circulates the radiation everywhere. Water quality is affected. We all eat the same fish. We use products from all over the world - if something is contaminated, it will cause harm.
Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.
In the Radiation Laboratory we count it a privilege to do everything we can to assist our medical colleagues in the application of these new tools to the problems of human suffering.
The study of celestial phenomena at radio wavelengths, radio astronomy came into being after the accidental discovery of cosmic radiation by radio engineer Karl Jansky in 1933.
