What else can I help you with?
When did Marie curie build radioactivity?
no but she built the knowleage of radioactivity.
Is radioactivity extensive or intensive?
is radioactivity extensive or intensive or chemical property
What are the differences between natural radioactivity nd artificial radioactivity?
Natural Radioactivity arises from radioactive components contained in nature. Artificial Radioactivity will come through element produced with in nuclear reactors as well as accelerators. Natural Radioactivity is a spontaneous process of disintegration. Artificial Radioactivity is carried in synthetically produced radioactive elements used in nuclear reactors.
How long can radioactivity be on uranium?
Radioactivity can persist on uranium for billions of years, as uranium has a very long half-life. The most common isotope of uranium, uranium-238, has a half-life of about 4.5 billion years. Uranium-235, another isotope, has a shorter half-life of about 700 million years.
Why do you choose isotopes with medium long half-lives as emitter in radiotheraphy?
Mainly for two reasons:to reduce as far as possible the radioactivity and hence reduce the radioactivity passive health effects; as the element radioactivity is inversely proportional to its the half live.To reduce as far possible the loss of the radioactive element through its radioactive decay during storage for non use.
Is radioactivity on the earth something relativity new?
no. radioactivity has been around since the earth's beginnings.
How long does radiation stay around?
Radioactivity gradually falls in all radioactive materials, how quickly it falls depends on the half-life of the material. The radioactivity of a material with a short half-life will fall alot quicker than the radioactivity of a material with a long half-life.
How has radioactivity been used to refine the geological time scale?
it has not
What has the author Jacob Rutt Risser written?
Jacob Rutt Risser has written: 'Neutron-induced radioactivity of long life in cobalt ..' -- subject(s): Cobalt, Neutrons, Radioactivity
How is radioactivity unnatural?
Radioactivity is 100% natural. It has been here since the first supernova star billions of years before the formation of earth about 4.5 billion years ago.
Why is radioactivity hazardous?
Radioactivity is hazardous because it emits ionizing radiation that can damage living cells and tissues, leading to health problems such as cancer, genetic mutations, and radiation sickness. Exposure to high levels of radioactivity can have serious and long-lasting effects on humans and the environment.
How does radioactivity affect the water cycle?
Radioactivity affect the water molecules. Radioactivity makes it harmful
Why would human hair be examined for radioactivity?
Well, there's always a possibility of anything emitting radioactivity once it has been around a radioactive source without gear/protection. All the best.
Advantages of nuclear radioactivity?
What other sort of radioactivity is there?
Radioactivity can be what?
Radioactivity can be induced in ordinary matter by artificial transmutation.
When did Marie curie build radioactivity?
no but she built the knowleage of radioactivity.
Do you messure radioactivity in literes?
You cannot measure radioactivity in litres
