Radioactive Decay
This form of radioactive decay increases atomic number by one, but does not change mass number.
Beta decay
This mathematical function represents half-life.
Exponential decay.
In a nuclear fission reaction, how does the mass of the products compare to the mass of the reactants.
The mass of the products is smaller.
In this medical diagnostic procedure, a patient is given a drug called a radiotracer. The radiotracer, a radioactive isotope with a short half-life, emits radiation, which is picked up by a scanner.
PET scan.
This term refers to low white blood cell counts. It is also a symptom of acute radiation syndrome (ARS).
Leukopenia
This form of radioactive decay releases mass number by 4.
Alpha decay
How much of a 1,000 gram sample of of radioactive fluorine-18 will remain after two half-lives?
250 grams
This is the minimum amount of mass/fuel needed to sustain a nuclear chain reaction.
The critical mass.
This form of radiation is powerful enough to rip electrons off atoms and molecules.
Ionizing radation
This scan uses X-rays to produce cross-sectional images of the body. It can detect fractures, tumors, and blood clots.
CT scan.
This form of radioactive decay has the greatest penetrating power.
Gamma decay.
The half-life of Element X is 60 minutes. How many half-lives will pass in one day?
24
This component of a nuclear reactor absorbs free neutrons, reducing reactivity.
Control Rods.
This isotope was one of the first used in the treatment of cancer. I hope this question isn't too COnfusing.
Cobalt-60.
DPTA, Potassium Iodide, Prussian Blue, and Neupogen are all examples of this.
Medicines given to people with Acute Radiation Syndrome (ARS).
This form of decay occurs when a nucleus absorbs an electron, resulting in the formation of a a neutron.
Electron Capture.
This is the magic number. Elements with atomic numbers greater than or equal to it are all radioactive and unstable.
83
This component of a nuclear reactor slows down neutrons produced by fission.
Moderator.
True or False - Ultraviolet radiation is an example of ionizing radiation.
True.
This term refers to skin redness. It is also a symptom of acute radiation syndrome (ARS).
Erythema
This form of radioactive decay decreases atomic number by 2.
Alpha decay.
After 10 years, 20 grams of a sample that originally weighed 80 grams remain. What is the length of the sample's half life?
5 years.
This component of a nuclear reactor is a radiation-absorbing material that is used to decrease exposure to radiation, especially gamma rays.
Shielding
True or False - Radiowaves are a form of ionizing radiation.
False.
This term refers to the technique in which the age of a fossil is estimated by checking to see how much Carbon-14 remains in it.
Carbon dating or radioactive dating.
