Learn how to get rid of radiation after a CT scan with these simple tips, such as staying hydrated and consuming foods high in antioxidants.


A computed tomography (CT) scan is a diagnostic imaging test that can help detect abnormalities in organs, tissues, and bones. A CT scan uses X-rays to create detailed images of the body from different angles.

Unfortunately, CT scans are associated with radiation exposure, which can increase a patient’s risk of developing cancer. Therefore, it’s important to take steps to address this exposure and get rid of the radiation after the exam is completed. In this article, we’ll explore some tips on how to get rid of radiation after a CT scan.

The importance of hydration

One of the simplest and most effective ways to remove radioactive isotopes from the body is through hydration. Drinking water helps flush out the isotopes through urine. Experts recommend drinking at least 64 ounces of water per day, but this amount should be adjusted based on the individual’s weight and activity level. Patients should also drink water at regular intervals throughout the day instead of guzzling large amounts all at once.

It’s important to note that CT scan patients may experience nausea or vomiting, which can make it difficult to drink water. In these cases, patients can try consuming small amounts of water or sucking on ice chips. Ginger tea or ginger supplements may also help alleviate nausea.

Consuming foods high in antioxidants

Radiation exposure results in the production of free radicals, which can damage cells. Antioxidants counteract the effects of free radicals and reduce their levels in the body. Consuming foods high in antioxidants can, therefore, help get rid of radiation after a CT scan.

Some foods rich in antioxidants include berries, nuts, leafy greens, and brightly colored fruits and vegetables such as carrots and tomatoes. Patients can incorporate these foods into their diet by adding berries to breakfast cereal, snacking on nuts, or making a salad with leafy greens and colorful fruits and vegetables.

Alternative imaging methods

In some cases, an ultrasound or magnetic resonance imaging (MRI) may be a better choice for diagnosis than a CT scan. Both imaging methods are non-invasive and do not use radiation. Patients can consult with their doctor about whether an ultrasound or MRI may be a suitable alternative to CT scans.

Patients can also consult with a medical imaging center to find facilities that offer non-invasive imaging methods.

Herbs and supplements

Some herbs and supplements have been shown to help remove radioactive isotopes from the body. For example, iodine supplements can help reduce levels of radioactive iodine, which is a common isotope used in medical imaging tests. Patients should speak with their healthcare provider before taking any supplements to ensure they will not interfere with other medications or health conditions.

Natural therapies

Natural therapies such as clay baths and specialized saunas can also help eliminate radioactive isotopes from the body. Clay baths can cleanse the skin of toxins, while specialized saunas use infrared light to promote sweating and toxin removal. However, it’s important to note that these therapies should be used with caution and only under the supervision of a healthcare provider to avoid any adverse reactions.

Patients can find providers of natural therapies through online directories or by asking their healthcare provider for recommendations.

Tips for reducing exposure in daily life

In addition to taking steps to reduce radiation exposure from medical tests, patients can also take steps to avoid radiation exposure in daily life. For example, using a headset for cell phone calls can reduce the amount of radiation absorbed by the head. Patients can also opt for non-x-ray alternatives for dental exams or stay indoors during a thunderstorm to avoid exposure to radiation from lightning strikes.


While CT scans can be a useful diagnostic tool, they come with the risk of radiation exposure. Patients can take steps to reduce the impact of this exposure by staying hydrated, consuming foods high in antioxidants, exploring alternative imaging methods, and using natural therapies. Reducing exposure in daily life can also help. Patients should consult with their healthcare provider to determine the best strategies for addressing their radiation exposure.
