Knowing the half-life of radioisotopes is useful for many reasons. We can look at a few examples to see why.
If we have radioactive material, we need to know the half-life to know how long it is dangerous. This applies to fission products inside spent nuclear fuel. This fuel generates heat long after it has been removed from a reactor, and we have to store this stuff securely for many human lifetimes. Fission products of uranium and plutonium are super nasty, and they must be kept out of harm's way.
Knowing the half-life of a certain material can allow us to date things that are old. Radiocarbon (carbon-14) is used to date things like skeletons or plant materials that archaeologists have recovered. We can also use something like uranium-lead to date rock structures back millions and even billions of years.
There is a broad range of radioisotopes that we find in use in the medical field, and we need to know the half-lives of them. We might select a short-lived radioisotope to act as a tracer for medical imaging. A medical staff member will inject a patient or will have him ingest this substance, and then medical professionals take pictures. Knowing the half-life allows us to prepare the material closely enough to the time of use so that it is "potent" enough for the application. In another use, a radioactive isotope will be implanted to irradiate a tumor in a patient. The half-life of the material must be known and coupled to the amount of the substance used to calculate dosage to a patient.
What else can I help you with?
How do you find the valency of atoms?
by knowing the no. of electorns in its outermost shell
What is one example of how engineers use their knowledge of atoms to create nee technologies?
Knowing the properties of atoms can allow the creation of new technologies. For example, doping silicon with impurities can allow the creation of semiconductors with superior/unique properties. These properties are a direct consequence of the electronic structure of the atoms, which in turn influences the band structure of the semiconductor. Thus, the knowledge of atomic properties can be used to produce useful materials.
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
How can electron dot diagrams can be useful?
They could be useful while determining the valency of atoms and the structures of chemical bonding in plausible ways.
Which model is helpful when predicting how atoms might bond?
The Bohr model is useful.
When was Illadelph Halflife created?
Illadelph Halflife was created on 1996-09-24.
How was sundial useful?
It was used to tell the time and knowing the time even the aproximate time is quuite useful
How do you find the valency of atoms?

Why are atoms and matter useful?
Because everything is comprised of them!
What are the names for groups of five, and can you provide an example of when knowing these names would be useful?
A group of five is called a quintet. Knowing this term can be useful when referring to a musical ensemble, such as a jazz quintet or a string quintet.
Will Valve be releasing a HalfLife 4?
Yes.
What is the secret to self esteem?
knowing that what you are is useful and valuable regardless of what others think
How useful is isotopes for dating bones a million years ago?
Just for knowing its origin
Why it is GCF very important?
When reducing fractions to their lowest terms knowing their gcf is useful

Why is swimming not useful?
Unless you're in water, knowing how to swim isn't useful. But if you end up in deep water, swimming will suddenly be very, very useful. Your life may even depend on it.
