Concept explainers
(a)
Interpretation:
Transuranium elements that have half-life more than 1000 year have to be determined using table 11-2 as the information source.
Concept Introduction:
Radioactive nuclides undergo disintegration by emission of radiation. All the radioactive nuclide do not undergo the decay at a same rate. Some decay rapidly and others decay very slowly. The nuclear stability can be quantitatively expressed by using the half-life.
Radioactive decay happens naturally. This can also be done artificially in the laboratory by means of bombardment reaction. Bombardment reaction produces synthetic nuclides. These synthetic radionuclides are known as transuranium elements. This is because they occur after uranium. The
(b)
Interpretation:
Transuranium elements that have half-life less than 1 hour have to be determined using table 11-2 as the information source.

- a 139 ng sample of radioactive material has a half life of 4.2 days how many ng of radioactive material is left after 3 half lives ?arrow_forward100 µc of a radioactive material injected in a patient. If its physical half life time is 30 days and the biological half life time is 80 days, then the remain activity after 80 days is Select one: O a. 250 uc O b. 500 µc C. 62.5 pc O d. 125 ucarrow_forwardThe decay of an isotope element follows a first-order reaction. Assuming that you start with 964 mg of the isotope element sample, after 39.4 hours of decay, you find that there is 275 mg of the sample remaining. What is the half-life time of this reaction?arrow_forward
- Technetium-99m (99m Tc) is a radioactive isotope commonly used in medical diagnosis. It emits gamma rays with a half-life of 6.0058 hours. A sample with activity 8.5 × 108 Bq is injected into a patient What percentage of this activity will remain after 28 hours? Give your answer as a percentage to 1 decimal place. Percentage of activity remaining: %arrow_forwardExplain how a scanning electron microscope (SEM) can be used in combination with an energy dispersive X-ray spectrometer (EDS) to perform elemental analysis on extremely small particles by placing the statements in the order that they occur. First step Last step Answer Bank An X-ray photon unique to the element composition of the atom is released.arrow_forwardThe radioactive isotope Yttrium-90 (Y-90, Z=39), a beta emitter, is used in cancer treatment and as a colloidal injection into large joints to relieve the pain of arthritis.

How many minutes will be required to heat the water if all of the energy generated from the decay is used to heat the water?arrow_forwardWrite the nuclear equation for the positron decay of C-11.arrow_forward
- Polonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006.
