Practice Radioactivity and decay, forms of radiation, uses and dangers with authentic MYP MYP Physics exam questions for both SL and HL students. This question bank mirrors Paper 1, 2, 3 structure, covering key topics like mechanics, thermodynamics, and waves. Get instant solutions, detailed explanations, and build exam confidence with questions in the style of MYP examiners.
A sample of a radioactive isotope is monitored in a laboratory. After a duration equivalent to exactly two half-lives, what percentage of the original unstable nuclei will remain undecayed?
When a nucleus of captures a neutron to become , how are its atomic and mass numbers affected?
In terms of atomic structure, why do certain nuclei undergo the process of radioactive decay?
In a nuclear fission reaction of , what are the primary products released in addition to the two smaller daughter nuclei?
Which of the following statements best describes the nature of radioactive decay for a specific individual nucleus?
A radioactive source has an activity of . After of observation, the activity is measured at . What is the half-life of this isotope?
Which of the following is correct regarding medical equipment that has been sterilized using high doses of radiation?
In an industrial process designed to monitor the thickness of thin aluminium foil, a beta-emitting source is typically used. Why would a gamma-emitting source be less effective than a beta source for this specific application?
The process of 'induced fission' in a nuclear reactor is initiated when a uranium-235 nucleus __________ a slow-moving neutron.
A radioactive sample initially contains undecayed nuclei. If the half-life of the substance is , how many undecayed nuclei will remain after have passed?
