Radiation is a part of our everyday lives. Background radiations are always in the environment. Most background radiation is emitted naturally, with only a minor percentage emitted by artificial components, emitted mainly by natural minerals, constantly present in our environment.
Fortunately, an average person is rarely subjected to uncontrolled radiation sources above background levels. Nevertheless, it’s a good idea to be prepared and understand what to do if you encounter a situation like this.
Understanding the radiation protection principles of time, distance, and shielding is among the greatest ways to be prepared. We can use & apply these concepts better to protect ourselves in the event of a radiological emergency.
We can use time, distance, and shielding to manage and limit our exposure to penetrating radiation and protect ourselves.
Reduce Time
By reducing the amount of time a person is exposed to a radiation source, the person’s exposure is decreased in direct proportion to the amount of time. The dosage absorbed is directly influenced by the amount of time spent near the radiation source; the less time spent near the source, the lower the radiation.
To avoid exposure as medical staff, examine a nuclear medicine patient prior to drug therapy instead of after the patient is administrated the medicine.
Increase The Distance
Increase the distance between you and the radioactive source when suitable. These sources can be sealed source and x-ray tubes. The inverse of the square of distance square reduces the exposure rate from the radiation source.
For instance, if a problem emerges during a fluoroscopy session, stand on the image intensifier side of the C-arm or simply step away from the patient when not assisting the doctor.
Use Shielding
Use radiation shielding, auto interlocking mechanisms, and in-place radiation monitoring devices for the third exposure management.
Concrete walls around a radiation oncology accelerator, portable shields, protective curtains, lead or lead comparable aprons can be integrated into the specific facility for radiation protection. Follow the seller’s guidelines for transportable x-ray devices.
What to do in case of a Radiation Emergency?
In the event of a radiation emergency, protect yourself, your family, and your pets.
- Get indoors or seek refuge.
- Stay inside to minimize your radiation exposure, and stay tuned for more information on what to do.
- Staying inside for at least 24 hours can safeguard you and your family until it is safe to leave the region since radioactive materials weaken with time.
In a Nutshell
By taking a few straightforward measures, you can effectively work near radiation sources:
- To decrease exposure, use time, distance, and shielding as stated above.
- Always wear dosimeters.
- Avoid direct contact with the contaminated area.
- Wear safety gear that can be changed if it becomes contaminated.
- Any part of the body that has come into contact with the radiation source should be washed with non-toxic soap and water.
- Consider that any items, equipment, or individuals that came into touch with the pollution are contaminated as well. Therefore, radiological monitoring is recommended before you leave the area.
