Isotopes of an element have different nuclear masses.
Isotopes of an element have the same number of protons.
Isotopes of an element have a different number of neutrons.
Isotopes of an element have the same atomic mass.
Which of the following statements describes why some forms of an element are radioactive.
Elements may be radioactive because they were exposed to too many gamma rays early on in the history of the Universe.
Elements may be radioactive because their nucleus is so unstable because there are way too many neutrons compared to protons inside the nucleus.
Elements may be radioactive because they have unstable electron clouds.
Elements may be radioactive because they have a very large atomic number.
In medicine and biology, you may need to work with radioactive isotopes. Which of the following particles are correctly matched with safety precautions. (Check all that apply.)
Gamma and X-rays require extremely stringent safety precautions that include the use of lead aprons.
Anyone that works with radioactive particles must use a dosimeter or badge that measures the amount of radiation exposure.
When working with alpha radiation, a simple piece of cloth or paper between the source and the worker will suffice as protection from exposure.
When working with beta radiation, a Plexiglass or other shield along with additional protective clothing is required by the worker.
Anyone working with radiation must get a license from the NRC.
Which of the following commonly used radioactive isotopes will have the shortest radiation exposure? In other words, half of the radiation will be gone over the shortest period of time?
Cobalt-60 with a half life of 5.27 years

Yes, it eventually decays into nothing.
No, radiation hovers near the limit of 0, but it never, ever disappears.
