Verify that the total number at nucleons, total charge, and electron family number are conserved for each of the fusion reactions in the proton—proton cycle in 1H+1H2H+e++ve,1H+2H3He+, and 2H+3He4He++1H+1H. (List the value of each of the conserved quantities before and after each of the reactions.)
Does the number of radioactive nuclei in a sample decrease to exactly half its original value in one halflife? Explain in terms of the statistical nature of radioactive decay.
Does loud irradiation leave the food radioactive? To what extent is the food altered chemically for low and high doses in food irradiation?
Large amounts of 65Zn are produced in copper exposed to accelerator beams. While machining contaminated copper, a physicist ingests 50.0 Ci of 65Zn. Each 65Zn decay emits an average ray energy of 0.550 MeV, 40.0% of which is absorbed in the scientist’s 75.0kg body. What dose in mSv is caused by this in one day?
Naturally occurring 40K is listed as responsible for 16 mrem/y of background radiation. Calculate the mass of 40K that must be inside the 55kg body of a woman to produce this dose. Each 40K decay emits a 1.32MeV , and 50% of the energy is absorbed inside the body.
decay producing 137Ba. The parent nuclide is a major waste product of reactors and has chemistry similar to potassium and sodium, resulting in its concentration in your cells it ingested.
decay producing 228Ra. The parent nuclide is nearly 100% of the natural element and is found in gas lantern mantles and in metal alloys used in jets (228Ra is also radioactive).
Since the uranium or plutonium nucleus fissions into several fission fragments whose mass distribution covers a wide tango of pieces, would you expect more residual radioactivity from fission than fusion? Explain.
decay producing 208Pb. The parent nuclide is in the decay series produced by 232Th. The only naturally occurring isotope of thorium.
To obtain the most precise value of the binding energy per nucleon, it is important to take into account forces between nucleons at the surface of the nucleus. Will surface effects inc lease or decrease estimates of BEN?
The particles emitted in the decay of 3H (tritium) interact with matter to create light in a glow- in-the-dark exit sign. At the time of manufacture, such a sign contains 15.0 Ci of 3H. (a) What is the mass of the tritium? (b) What is its activity 5.00 y after manufacture?
The ceramic glaze on a red-orange “Fiestaware” plate is U2O3and contains 50.0 grams of 238U, but very little 235U. (a) What is the activity of the plate? (b) Calculate the total energy that will be released by the 238U decay, (c) If energy is worth 12.0 cents per kWh , what is the monetary value of the energy emitted? (These brightly- colored ceramic plates went out of production some 30 years ago, but are still available as collectibles.)
