These systems do have a chance of breakdown per unit of time, that increases from the moment they begin their existence.

In a human body of 70 kg mass, about 4,400 nuclei of 40K decay per second.

Alpha decay, the release of a high energy helium nucleus, is the most common form of radioactive decay for plutonium.

In nuclear physics, a decay product (also known as a daughter product, daughter isotope or daughter nuclide) is the remaining nuclide left over from radioactive decay.

The cell wall is a very thin primary cell wall .

Because muons have a very large mass and energy compared with the decay energy of radioactivity, they are never produced by radioactive decay.

Shortly after the discovery of the neutron in 1932, Enrico Fermi realized that certain rare beta decay reactions immediately yield neutrons as a decay particle (neutron emission).

Do you have a cellphone?

Do you have a smartphone?

The phone rang.

Actinium 227 is a decay product of uranium 235.

My new phone is thinner than my old phone.

Proteins are also important in cell signaling, immune responses, cell adhesion, active transport across membranes, and the cell cycle.

The primary decay products of ytterbium isotopes lighter than 174Yb are thulium isotopes, and the primary decay products of ytterbium isotopes with heavier than 174Yb are lutetium isotopes.

W bosons The W bosons are best known for their role in nuclear decay.

More sophisticated models are used to predict orbital decay of satellites.

Each radioactive isotope has a characteristic decay time period the half life that is determined by the amount of time needed for half of a sample to decay.

While alpha decay was seen only in heavier elements of atomic number 52, tellurium, and greater, the other two types of decay were seen in all of the elements.

It's the mobile phone.

My mobile phone was dead.

I want a cellular phone.

Do you have a cellphone?

I need to charge my mobile.

I need to charge my cell phone.

Charge your phone.

I love this mobile phone.

My cellphone has been stolen.

I don't have a cellphone anymore.

Where's your phone?

I don't have a cellphone.

My cellphone is ringing.

Tom doesn't have a cell phone.

Ah, I forgot my mobile phone.

I didn't have a phone.

Tom lost his phone.

I want this telephone.

I want this phone.

Turn off your cellphone.

Where's the cellphone?

And so I thought, Maybe if it can promote cell growth, it can inhibit cell death, too.

Beta decay either increases or decreases the atomic number of the nucleus by one.

For a general introduction and description of exponential decay, see exponential decay.

In the experiments, the alpha decay of three atoms of ununoctium was observed.

Also, the mu meson's decay products included both a neutrino and an antineutrino, rather than just one or the other, as was observed in the decay of other charged mesons.
