Those of us who have seen the prototypes know that this product could be insanely popular. ( I think it could make 50% of televisions & computer screens obsolete.
Half-life is defined as the time it takes for one half of a radioactive element to decay into a daughter isotope. As radioactive isotopes of elements decay, they lose their radio activity and become a brand new element known as a daughter isotope.
A knowledge of radioactive half-life is important because. It enables the dating of artifacts. It allows us to calculate how long we must store radioactive waste until they become safe. It enables doctors to use safe radioactive tracers. Half-life is the time it takes for one-half of the atoms of a radioactive material to disintegrate. Scientists can use the half-life of carbon-14 to determine the approximate age of organic objects. They determine how much of the carbon-14 has transformed. They can then calculate the age of a substance.
