No, radioactivity is not new. It has existed since the formation of Earth and is a natural phenomenon. The discovery and understanding of radioactivity by scientists in the late 19th and early 20th centuries brought attention to its presence in the world.
no but she built the knowleage of radioactivity.
is radioactivity extensive or intensive or chemical property
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.
One thing is that now the correct age of the earth could be calculated. Before radioactivity was discovered the earth was though to have cooled enough to be only about 25 million years old by calculation. The discovery of radioactivity changed all that by increasing the heat the earth could radiate and so increasing the age of the earth dramatically.
The nucleus would first show an increase in radioactivity as it contains the genetic material of the cell, and radioactivity affects DNA.
no. radioactivity has been around since the earth's beginnings.
Radioactivity affect the water molecules. Radioactivity makes it harmful
This process through which unstable nuclei emit radiation is called radioactive decay. It also is called nuclear decay, and it is a natural process in which an atom of an isotope decomposes into a new element.
What other sort of radioactivity is there?
Radioactivity can be induced in ordinary matter by artificial transmutation.
no but she built the knowleage of radioactivity.
You cannot measure radioactivity in litres
Radioactivity in Japan is about 15,000 terabecquerels.
false
Anything works to stop radiation but lead is effective, safe and easy to handle, and relatively inexpensive. Seriously, check cost of lead vs depleted uranium.
NO. Henri Becquerel was the discoverer of radioactivity.
You need radioactivity, for many things such as x-rays.
