Radiation Illness Revision Notes

Radiation Injuries
Exposure to radiation may lead to
- Local tissue injury
- Acute radiation syndrome
Pathophysiology
4 types of ionising radiation
- alpha particles
- beta particles
- gamma & x-rays
- neutrons
Each type has different physical properties and cause a variable degree of tissue damage.
Types of exposure
External irradiation
- whole body irradiation, but nothing contaminates the body or clothing
- patient is not radioactive and no risk to others
Contamination
- radioactivity contaminates the patient
- externally on clothing and skin
- internal - inhaled, ingested
- continual irradiation whilst contaminated
- of risk to others especially if external contamination
Incorporation
- of radioactive atoms into the patient’s tissues e.g iodine in thyroid tissue, phosphorus to bone
