An unstable atomic nucleus breaks apart, and converts into another atom. Some radiation will also be emitted.
Each type of atom (each isotope) has a characteristic half-life; for example, Tritium (3H - a hydrogen atom consisting of one proton and two neutrons) has a half-life of about 19 years. This means that if you have a large number of Tritium atoms, after 19 years half of them will have broken apart - changed into something else. However, you can't predict when an individual atom will break apart - except that there is a high probability that it will happen after a few times the half-life, at the most.

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 occurs spontaneously in certain elements without human intervention, while artificial radioactivity is induced through processes like nuclear reactions or bombardment of nuclei with particles. Natural radioactivity is present in materials like uranium and thorium, whereas artificial radioactivity typically involves isotopes produced in nuclear reactors or accelerators. Both types of radioactivity emit radiation, but the sources and mechanisms differ.
Which cell component would first show an increase in radioactivity?
The nucleus would first show an increase in radioactivity as it contains the genetic material of the cell, and radioactivity affects DNA.
How long has there been radioactivity?
Radioactivity has existed since the formation of the Earth around 4.5 billion years ago. The discovery of radioactivity date back to the late 19th century, with Henri Becquerel and Marie Curie being prominent figures in its study.
What is a principle of radioactivity?
Radioactivity represent instability in the nucleus of the atom. Various forces, the strong interaction or binding energy, the electromagnetic interaction, and the weak interaction, all participate in the seeming magical relationships that create radioactive and non-radioactive (stable) isotopes.
What does ALARA mean in terms of radioactivity?
ALARA stands for "As Low As Reasonably Achievable." It is a principle to minimize radiation exposure by keeping it as low as possible without sacrificing the benefits of the radiation source. ALARA is used to guide practices and regulations in industries and activities involving radioactivity to protect workers and the environment.
How does radioactivity affect the water cycle?
Radioactivity affect the water molecules. Radioactivity makes it harmful
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.
Do you messure radioactivity in literes?
You cannot measure radioactivity in litres
How much radioactivity is in Japan?
Radioactivity in Japan is about 15,000 terabecquerels.
What is the power formula for radioactivity?
The power formula for radioactivity is given by P = λ*N, where P is the power, λ is the decay constant, and N is the number of radioactive atoms. This formula represents the rate at which energy is released by radioactive decay.
When did Marie curie build radioactivity?
no but she built the knowleage of radioactivity.
What do you need radioactivity for?
You need radioactivity, for many things such as x-rays.
Which elents cannot be diffused by radioactivity also?
Radioactivity has nothing to do with diffusion.
Marie curie discovered radioactivity?
NO. Henri Becquerel was the discoverer of radioactivity.
