12 Questions
What is the process called when an unstable isotope undergoes changes to reach a stable state and emits radiation?
Radioactive decay
What is the composition of an alpha particle?
2 protons and 2 neutrons
What is the range of alpha particles penetration in air?
5 cm and less
What is the effect of alpha particles on cells?
They damage cells by breaking down DNA
What is the characteristic of beta particles?
They are fast and light
In which elements does alpha-decay occur?
Very heavy elements
What is the characteristic of gamma rays that allows them to have a high penetrating power?
They have no mass and no charge
What is the primary purpose of diagnostic radiopharmaceuticals?
To be used in tracer quantities for diagnosis
What is the main reason why radiopharmaceuticals should be sterile?
Because they are administered parenterally
What is the somatic effect of radiation exposure that can appear after years of exposure?
Severe anemia
What is the purpose of tagging a radionuclide to a pharmaceutical?
To enable the detection of radiations emitted by the pharmaceutical
What is a characteristic of the pharmaceutical of choice for radiopharmaceuticals?
It should be safe and nontoxic for human administration
Test your knowledge on the process of radioactive decay, where unstable isotopes transform into a stable state, emitting radiation such as alpha, beta, and gamma particles. Learn about the different types of decay and the particles involved.
