Which radiation type does not pose an external hazard but can be hazardous if ingested or inhaled?

  1. Gamma radiation

  2. Beta radiation

  3. Alpha radiation

  4. Neutron radiation

The correct answer is: Alpha radiation

Alpha radiation does not pose an external hazard, meaning it cannot penetrate through the skin and affect the body. However, it can be extremely hazardous if ingested or inhaled because it can cause damage to internal organs and tissues. Gamma radiation, on the other hand, is a type of electromagnetic radiation that can penetrate through the body and pose an external hazard. Beta radiation can also pose an external hazard, although it is less penetrating and less hazardous than gamma radiation. Neutron radiation is a type of radiation that can pose both an external and internal hazard, depending on the source and dose. However, it is not known to be hazardous if ingested or inhaled.
