Should Radioactive isotopes used for medical purpose have long lives?

Radioactive isotopes used for medical purpose should not have long lives. The imaging cameras need to pick up the particles from the decay of the radioactive nuclei, and having a lot within an hour or two means a short half-life.

How many isotopes does ruthenium have?
A regular ruthenium atom has 44 electrons. But there are forms of atoms called ions, which have 1 or more extra or less electrons.
Is rutherfordium harmful?
Rutherfordium is a synthetic element and its properties are not well-studied. However, it is expected to be highly radioactive and potentially harmful due to its radioactive decay. As with other radioactive elements, proper safety measures and handling protocols should be followed to minimize the risk of exposure.
Do radioactive isotopes release neutrons?
No. isotopes are radioactive because the ratio of protons to neutrons is not right. As proton # increases, more and more neutrons are needed to maintain nuclear stability. If an atom has too many, or too few neutrons, it will be radioactive. Excess (or deficient) electrons are call ions.
What is the difference between Chemical kinetics vs Chemical decay?
Chemical decay, also known as radioactive decay, is a process that occurs naturally (usually in isotopes or unstable substances) Chemical Kinetics is one of the ways you can analyze radioactive decay. Although it should be noted that radioactive decay undergoes first order decay when using Chemical Kinetics.
Are radioactive isotopes used to determine the absolute age of rocks?

Is rabbit feces radioactive?
No. There is no reason why rabbit feces should be radioactive, unless of course they ate something radioactive or they are under medical care using radioactive isotopes. It might be possible that if the soil is radioactive, and the plants become radioactive, that a rabbit might excrete radioactive feces from eating the plants.

Why is lead mixed in with all deposits of uranium?
Because the stable isotopes of lead are the end products of the decay chain of uranium natural radioactive isotopes. or because lead is the product of decayed uranium... that should be a good enough answer for your chem teacher you cheater!

What is the longest radioactive halflife?
First, it isn't very accurate to talk about a radioactive "element"; you should talk about radioactive isotopes. Different isotopes of the same element can have very different behavior in this sense. For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years).Individual atoms, in a radioactive isotope, will decay at a random moment. The half-life refers to how long it takes for half of the atoms in a given sample to decay (and convert to some other type of isotope).

What are two uses of isotope?
Geologists can determine the ages of rocks and fossils by analyzing the isotopes found in them. Radiation from certain isotopes can be used to treat cancer and to kill bacteria that cause food to spoil. Radioactive isotopes can also be used as labels or "tracers" to follow the movements of substances within organisms.
What should you do if your poop is radioactive?
stop eating radioactive food.....
Should density for aluminum be the same for all aluminum samples?
No. Because Al has a large no. of isotopes. (i think 22 isotopes).
How do you use radioactive element in a sentence?
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
