Geology Exam #4 Questions With Answers What is a parent isotope? A daughter? Parent Isotope: An isotope that undergoes decay to form a daughter isotope Daughter Isotope: May be stable or may decay to form another daughter (formed from the parent isotope) What is a half‐life? The time required for 1/2 of a radioactive isotope to decay ion a stable daughter isotope What is meant by mass wasting? The general term for all gravity induced movement of material down a slope. How a...

If an unshielded sample of radioactive material emits alpha particles, what effect will it have on a person sitting in the next room? (Assume the wall between rooms is composed of concrete.) - None, because the wall will block the radiation. In which isotope is the strong nuclear force not strong enough to balance electrostatic forces between protons? - uranium-238 A radioactive nuclide that is used for radiation therapy for cancer has 33 neutrons and a mass number of 60. Which is the corr...

REHS EXAM-RADIATION USES AND PROTECTIONIn many cases, x-ray beams or fluoroscopes will extend past the fluoroscopic screen and protective lead, thereby exposing the operator to the direct beam. a.
