Final answer:
The question addresses occupational ionizing radiation exposure and its health risks, including cancer and genetic defects, with a focus on the physics of radiation measurements, biological effects, and doses experienced during medical imaging.
Step-by-step explanation:
The question concerns annual occupational exposure to ionizing radiation and its effects, particularly relating to cancer and genetic defects. When evaluating exposure, it is essential to consider sources such as medical imaging and background radiation, as well as the biological impact ionizing radiation can have on the body.
Risk assessments for occupational exposure to radiation, as the plumber's scenario at a nuclear power plant, involve calculating the increased risk of cancer or genetic defects due to radiation. The biological effects of ionizing radiation, such as those from medical imaging techniques, can range from negligible to significant, depending on the dose and type of radiation. The doses for common medical imaging procedures vary, with a chest X-ray amounting to about 0.1 mSv, while more intense procedures like a CT scan can yield around 10 mSv.
As for the term 'picowave', it was used historically in the context of food irradiation and related to the photon energy in MeV for a given wavelength. Calculating the energy in MeV of a picometer photon requires understanding of electromagnetic spectrum and the relation between energy, frequency, and wavelength. Lastly, the mass of 1.00 µCi of a radioisotope is determined by its specific activity and the half-life of the isotope involved.
