It is not necessary for a half life to be long. Some isotopes have half lives of just a few seconds, or even less.

Why are some isotopes half-lifes?
Each isotope has a different rate of radioactive disintegration characterized by the half-life, the time necessary to reduce by half the number of atoms.
How long is the half life of radioactive water?
The half life of radioactive water depends on what radioactive nuclides are present in the water.
How long is berkelium's half- life?
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
Why a geiger counter gives a lower counting rate for radioactive material that has a long half life than does with short half life?
The count rate observed by a Geiger counter is proportional to activity, not to half-life.
Half-life of a radioisotope is?
The half life of a radioisotope is the time taken for the number of radioactive atoms to decay to one-half. A free neutron has a half life of 10.6 minutes. The half life of carbon 11 is 20.3 minutes. Many isotopes have very short half lives, and many have very long ones.
How long is plutonium active in radiation?
Plutonium remains radioactive for a long time as the half life is 87.7 years for Pu-239. The half life is how long it takes for half of the radioactivity to dissipate.
Why are some isotopes half-lifes?

How long is radium's half life?
It is about 1600 years.
How long have you been in US?
Almost half my life.
As a sample of a radioactive element decays its half-life?
No, the half life remains exactly the same throughout
How long is the half life of radioactive water?
The half life of radioactive water depends on what radioactive nuclides are present in the water.
How long is berkelium's half- life?
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotope?
One half life.
What is the sperm cell function?
Its function - is to supply half the genetic material necessary to create a new life.
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotopes?

What does half-life tell about a radioisotope?
How long it takes for half of a sample to decay to another form.
