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.
How long is berkelium's half- life?
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
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.
Why a geiger counter gives a lower counting rate for radioactive material that has a long half life than does with short half life?
A Geiger counter detects radiation by counting the number of decay events that occur. Radioactive material with a long half-life decays more slowly, resulting in fewer decay events per unit time compared to material with a short half-life. Therefore, the Geiger counter will record a lower counting rate for radioactive material with a long half-life.
Is half life of any importance in selecting a radioisotope?
Yes, the half-life of a radioisotope is important in selecting one for a particular application. For example, a short half-life is suitable for medical imaging to minimize patient radiation exposure, while a long half-life is preferred for industrial applications requiring long-term monitoring or storage. It also affects the decay rate and stability of the isotope.

How long have you been in US?
Almost half my life.
How long is radium's half life?
It is about 1600 years.

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 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 does half-life tell about a radioisotope?
How long it takes for half of a sample to decay to another form.
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 long does a half of a 37.5 adepex stay in your system if you only took a half?
the half life of phentermine is 16 to 31hrs
What is the sperm cell function?
Its function - is to supply half the genetic material necessary to create a new life.
If it were 2 hours later it would be half as long?
If its linear half-life were 2 hours, then yes.
