The nurse is teaching a group of student nurses about radiation therapy. Which would the nurse include in the teaching?

Select all that apply.
  1. The dose is always more than the exposure.
  2. Clients receiving brachytherapy are radioactive.
  3. Clients receiving teletherapy are not radioactive.
  4. Beta particles are the most common type of radiation therapy.
  5. Bodily waste from a client receiving brachytherapy does not require special handling.
Numbers 2 and 3 are correct.
Rationale: Clients undergoing brachytherapy have radioactive isotopes inside the body and are radioactive and potentially hazardous to others. Their bodily wastes are radioactive and require special handling until the isotope is completely eliminated from the body. Teletherapy uses a source of radiation outside the body; therefore, these clients are not radioactive. The dose is always less than the exposure because of energy loss on the way to the target tissue. Gamma rays are most commonly used for radiation due to their ability to deeply penetrate tissues.
