RADIATION EXPOSURES
This is the average does to the general population of the US from consumer products as part of man-made consumer products.
What is 12 mrem/year?
This is the largest contributor of man-made background radiation to the average general population.
What is Medical Exposures?
The is how the curie (Ci) is defined.
This is stable isotope in which all three of the naturally occurring radioactive decay chains end.
What is Lead?
This source of natural and man-made background radiation contributes to the largest average dose to the general population.
What is Internal Emitters (food chain)
This is the average dose equivalent of the general population from natural internal emitter (food chain) background radiation.
What is 31 mrem/yrear?
What is less than 1?
This is the half-life of Ar-41 according to the Chart of the Nuclides.
What is 1.82h?
This is the unit of absorbed dose.
What is Rad?
This is the factor which contributes the greatest variability in dose from natural cosmic background radiation.
What is Altitude?
What is 18 mrem/year?
This is the radionuclide generally considered to be the greatest contribute of dose from internal emitters (food chain) as part of natural background radiation sources.
What is Potassium-40?
This is how to trace the most probably decay path of SR-90 to a stability.
What is B- to Y-90, B- to Zr-90m, y to Xr-90?
This is defined as the property of certain nuclides of spontaneously emitting radiation.
What is Radioactivity?
This is the unit of dose equivalent.
What is Sievert?
This is the average annual effective dose equivalent to the general population from inhaled radionuclides (primarily radon) as part of natural background radiation.
What is 230 mrem/year?
These are the two elements whose radionuclides are generally considered to the greatest contributors of dose equivalent from natural terrestrial background radiation sources.
What is Uranium and Thorium?
This represents the activity of the sample after 1.25 hours when the initial activity of a radioactive sample is known to be 1.0 x 10E12 dpm. The half-life of the nuclide of concern is known to be 15 minutes.
What is 3.13 x 10E10 dpm?
This is defined as the ionization produced by x- and gamma radiation in air.
This is the amount of energy deposited per unit mass.
What is Absorbed Dose?
This is the average dose to the general population from all combined medial exposures as part of the man-made background radiation sources.
What is 298 mrem/year?
This is the factor which contributes the greatest variability in dose from natural terrestrial background radiation.
What is Geology?
This is the answer sample should you prepare to achieve the required activity at the start of the experiment when you are charged with preparing a radioactive sample for use. The experiment is scheduled to start in 5 hours, the half-life of the nuclide you are preparing is 84 minutes. The activity sample at the beginning is required to be 2.5 x10E6 dpm.
What is 2.97 x 10E7dpm?
This is defined as the length of time required for one-half of the original number of nuclei to disintegrate.
What is the Radioactive half-life?
This is the process by which a nucleus spontaneously disintegrates by one or more discrete energy steps until a stable state is reached.
What is Radioactivity?
