CT Scan Room Safety: You Must Know about


A computed tomography (CT) scan is a diagnostic tool used to create detailed images of various parts of the body.  With it, doctors can see bones and soft tissue. Scanning almost any part of the body and using it to diagnose a variety of medical conditions including cancer and more.

There is radiation exposure, so if you are pregnant or suspect you might be pregnant, please speak with your doctor before the exam.

However, due to the radiation involved, it is essential that certain precautions need to follow to keep both patients and healthcare professionals safe. 

Why CT scan is done?

The CT scan helps to identify and monitor the various medical conditions or issues in the body. It provides more detail than the X-Ray Machine. There is movement of the beam in a circular motion, which allows capturing of more detailed images of the single organ from different angles.  

Also help diagnose tumors, and internal bleeding, or check for other internal injuries or damage and for a tissue or fluid biopsy. It shows detailed images of bones, muscles, fat, organs, and blood vessel. 

CT Scans with Contrast

Sometimes the CT scan is with the contrast. Contrast is defined as the substance that is taken orally through the mouth or injected into the IV line. It causes the particular organ or tissue to study and see clearly. 

In case of a recent illness severe or moderate or any kind of allergy,  you must inform the doctor before the exam. The Seafood allergy is not considered to be a contra-indication for the iodinated contrast, as reported. 

What to know before your exam?

  1. The CT scan will last for approximately 15 minutes, but it completely depends on the type of scan. 
  2. If the scan is with the Contrast, make sure not to eat or drink 4 hours before your exam. 
  3. Always discuss the exam with your doctor regarding the pre-exam effects and precautions and the post-exam effects. 

Precautions need to be taken during the exam

  1. All patients (and visitors) must wear protective clothing such as lead aprons that shield them from radiation exposure.
  2. The shielding material will depend on which type of scan has been requested by their doctor.
  3. No metal objects (such as jewelry or watches) inside the room.
  4. These could interfere with the machine’s readings and make it difficult for the radiologist to interpret results correctly.
  5. Shoes should also not contain any metallic components, such as iron inserts because they could potentially block part of your body from being scanned accurately enough. 
  6. It is advisable to remove all electronic devices – including cell phones.
  7. Patients should always inform their doctor/radiologist about any metal fragments inside the body.
  8. Including dental fillings or thick scar sections along their chest because the phase affected is left unnoticed.  
  9. It is important for patients to inform their physician if they are pregnant since X-ray exposure could harm developing embryos and fetuses. 
  10. Certain medications interact negatively with radiation exposure, so ensure your doctor has been informed about all current medicines.
  11. Diabetic People: They can eat a light breakfast or lunch prior 3 hours before the exam. Discontinuation of your medication for 3-4 hours. The doctor will give detailed instructions.  

During the Scan

  • You will lie on the scan table that slides into the large circular opening of the CT Scan Machine. 
  • CT Scanner will begin to rotate around the body, and the X-rays will pass through the body. During this, you will hear a clicking sound. 
  • The computer will absorb and transmit the X-rays and will transform the information into images; interpreted by radiologists.  
  • It is important to remain still during the procedure to monitor clear images. 

After the Scan

  • If you have taken the contrast media, they may monitor you for some period of time for any side effects or reactions like itching, rashes, or any.
  • There is no special type of care needed after the scan, you can resume the activities and diet if your doctor doesn’t advise you differently. 

Taking precautionary measures helps keep both personnel operating as well as patients receiving treatments safe from potential radiative harms caused due to incidence direct contact or inappropriate usage practices. 

Ensuring those involved do indeed adhere to strictly prescribed protocols governing these powerful pieces of medical technology will go far in protecting the long-term well-being of those impacted by their users alike.

Importance of Radiation Jackets

Computed Tomography (CT) Or Computerized Axial Tomography (CAT) scan is a diagnostic tool that identifies and monitors the diseases inside the body. It creates detailed images or scans of the body.

Modern CT machines are more advanced and fast, produce better quality 3D images of the areas inside the body, and also detect abnormalities better. It is widely used to diagnose cancer, circulatory diseases, coronary artery diseases, blood clots, and almost every area of the body. 

During the CT scan, there is radiation exposure, it uses X-Rays, which are a form of ionizing radiation. Exposure to Ionizing Radiation increases the risk of cancer. 

What is Radiation?

Radiation is the emission of energy in the form of waves or particles which travel through space carrying with them electromagnetic energy.

It can be natural, where it occurs in nature and has no effect on humans or other living organisms, or artificial such as an imaging machine produces radiation.

Radiation plays an important role in many scientific fields including medical imaging, astronomy research, and astrophysics. Additionally, it has numerous applications in engineering disciplines such as welding and industrial radiography.

Types of Radiation: Ionizing & Non-Ionizing

Ionization occurs when electrons become separated from their atom’s nucleus. It creates ions that can damage molecules in living organisms causing DNA mutations and cellular damage including cancerous cells.

Most forms of non-ionizing radiation do not have enough energy to break apart atoms reliably into ions. Government agencies such as OSHA (Occupational Safety & Health Administration) monitor safety hazards that they pose.

Radiation Exposure

Everyone exposed to some kind of exposure whether in natural form or artificial form. We are regularly exposed to various kinds of radiation like radioactive materials. It includes radon a radioactive gas that comes from the natural breakdown of the uranium in soil, water, rocks, and building blocks, and cosmic rays from outer space; known as background radiation.

Background radiation varies from country to country. The largest source of this is radon which is typically about 2 mSv per year, a natural gas found in our homes. Location is also important, being at a higher altitude increases a person’s exposure.  

The average radiation one should take is 3 millisieverts per year(mSv).

Radiation from CT scan machines is ionizing radiation, including X-rays, Cosmic rays, and radiation from radioactive materials. Depending on how many slices and how much detail we need, these machines vary the amount of radiation used.

Risks with the Radiation Exposure

However, there are risks involved with using a CT scan. Exposure to these high levels of radiation can potentially have long-term physical health effects on individuals who use them too often.

Modern scanners keep patient doses as low as possible. Medical professionals should regularly monitor the level of doses to ensure the safety of patients.

Experiencing some amount of radiation is unavoidable during such scan treatments. Preventive measures like proper shielding materials, controlling on/off times, and monitoring patient dosages can help that risks from these devices are kept to an absolute minimum. 

Most medical uses of radiology produce small doses of ionizing radiation. It is important to be aware of this potential risk factor associated with CT scanning. Also, talk about risks and precautions with your health professional before undergoing any test. 

At very high doses, the radiation can damage the functioning of the tissues and organs and also causes nausea, vomiting, and radiation burn. Excessive exposure to radiation doses can increase the risk of various types of cancer.

Nuclear emergencies can release radioactive iodine, which can increase the risk of Thyroid Cancer if breathed in or taken in. It is important for children as well as adults to take precautions. 

Radiation Jackets

They are an important form of protection against radiation exposure. It serves to protect individuals from exposure by blocking or shielding them from dangerous amounts of radiation-causing particles or rays, such as X-rays and gamma rays.

Reduce or even completely eliminate any potential radiation-related illnesses by providing a barrier between the person and the source of radioactive material in their environment.

Various protective layers inside them absorb most forms of harmful radioactive particles coming into contact with their wearers’ body surfaces when they design these specialized garments.

Thus, ensuring an effective level of safety for those handling such materials or entering areas where higher levels may be present. 

Radiation Jackets importance

By wearing a radiation jacket, people can properly protect themselves when working with materials that may contain harmful amounts of radiation and potentially extend their lives.

The importance of radiation jackets lies in their ability to shield individuals while allowing them access to areas with potentially high levels of ionizing or non-ionizing electromagnetic fields. Its features include lightweight breathable materials, adjustable straps for ease of movement, and an airtight seal that keeps out external elements like dust particles.

A radiation jacket provides protection against harm while allowing maximum freedom and mobility without compromising safety standards. It comes with features such as adjustable straps and collars that make them comfortable to wear for long periods of time while still providing excellent levels of protection from harmful X-ray or Gamma ray radiation sources. 

Users shall use appropriate radiation protection devices such as barriers, aprons, goggles, and thyroid shields during the operation of X-ray equipment. Verify these devices periodically for their shielding adequacy.
