A 46 year old male has been exposed to beta radiation during a radiation test. Which of the following statements are true?

The key idea is distinguishing exposure from contamination in radiation safety. When someone is exposed to beta radiation, it means they received radiation from a source, but that does not automatically make the person radioactive. A patient becomes a source of radioactivity only if radioactive material is on or inside them (contamination). If there is no contamination, they are not a significant source of radioactive emissions. Beta radiation has limited penetration and is generally easy to shield against with routine precautions. You don’t typically need an air‑purifying respirator unless there’s a specific inhalation risk from radioactive material. A lead barrier is not required for caring for a patient simply exposed to beta radiation, because shielding for beta is usually accomplished with gloves and standard personal protective measures, not a heavy barrier. Therefore, if there’s no contamination, the patient poses little risk of contaminating you or your partner. If contamination were present (radioactive material on skin, clothing, or in excretions), then stricter containment and shielding would be indicated. The core concept is that exposure does not equal contamination, and true radioactive sources are defined by the presence of radioactive material on or in the patient.
