What Is a Thyroid Collar?

Thyroid collars play a vital role in radiation safety during medical imaging and interventional procedures. Designed to protect one of the body’s most radiation-sensitive organs, thyroid collars are essential for radiology professionals, physicians, surgeons, and patients who are exposed to diagnostic or interventional radiation. Understanding what a thyroid collar is, how it works, and how to use and maintain it properly is key to ensuring safety and regulatory compliance in today’s imaging environments.

Why Is It Important?

A thyroid collar—sometimes called a thyroid shield—is a protective garment made with lead or lead-equivalent materials. It is worn around the neck to shield the thyroid gland from ionizing radiation and scatter during imaging procedures such as X-ray, fluoroscopy, and CT-guided exams. The thyroid gland is highly sensitive to radiation exposure. Even relatively low doses can increase the risk of long-term thyroid disorders, including cancer. Because of this sensitivity, radiation safety guidelines strongly emphasize protecting the neck whenever radiation exposure is possible. A properly worn thyroid collar helps block stray radiation, significantly reducing the dose received by the thyroid and supporting safe working conditions for staff and patients alike.

How Is a Thyroid Collar Used?

Thyroid collars are worn snugly around the neck and are usually secured with Velcro or adjustable fasteners. They are most often used together with lead aprons or vests to provide full upper-body radiation protection. For healthcare professionals, thyroid collars are part of standard personal protective equipment when working in areas where radiation exposure is frequent or prolonged. For patients, thyroid collars provide an extra layer of protection during imaging of the head, neck, or chest when shielding does not interfere with diagnostic quality or body part being imaged.

Best Practices for Use

• Proper fit: The collar should sit comfortably around the neck without being tight or restrictive.

• Correct positioning: It should cover the thyroid area while staying out of the imaging field. (for patients)

• Use with other shielding: Thyroid collars should always be used in combination with lead aprons or other protective garments.

Are Thyroid Collars Safe?

Yes. Thyroid collars are designed specifically to reduce radiation exposure while remaining comfortable and easy to wear. When fitted properly, they provide effective shielding without interfering with movement or workflow. Research shows that thyroid shielding can dramatically reduce radiation dose to the neck, helping limit cumulative exposure over time. For staff who work around radiation daily, this protection is especially important.

How Should Thyroid Collars Be Cleaned?

Because thyroid collars are worn close to the skin and frequently shared between users, proper cleaning and disinfection are essential for infection control. Over time, protective garments can collect bacteria, germs, and bodily fluids. Routine cleaning helps protect both staff and patients while also extending the life of the garment.

Recommended Cleaning Steps

1. Use approved disinfectant wipes that are safe for radiation protection garments.

2. Wipe the entire surface of the collar, including seams and edges.

3. Allow to dry completely by hanging or laying flat without creases.

4. Clean after each use to prevent buildup of bacteria and contaminants.

5. Schedule periodic deep cleaning as part of a comprehensive radiation safety program.

Proper maintenance helps ensure thyroid collars remain hygienic, effective, and compliant with infection control standards.

Can You Wear a Thyroid Collar Someone Else Used?

Yes — as long as it has been properly cleaned and disinfected. In medical environments, shared protective equipment is common, but strict hygiene protocols must be followed between uses. Facilities should have clear procedures for disinfecting radiation protection garments, and staff should never wear a collar that has not been cleaned according to policy.

Choosing the Right Thyroid Collar

Not all thyroid collars are the same. When selecting a thyroid collar, it is important to consider:

• Proper fit and adjustability

• Lead or lead-equivalent protection level

• Comfort and style

• Ease of cleaning and maintenance

Modern lead-equivalent materials provide excellent radiation protection while being lighter and more comfortable than traditional lead.

Radiation protection is not something you can afford to guess about — especially when it comes to lead aprons. Whether you manage a small imaging center or a multi-room hospital department, your lead apron inventory plays a critical role in protecting your staff, your patients, and your compliance standing.

Yet in many facilities, lead aprons are treated as “set it and forget it” items — hung on a rack, used daily, and rarely reviewed until something goes wrong.

A radiation protection audit can help you answer one very important question:

Is your lead apron inventory actually doing its job?

What Does “Up to Code” Really Mean?

Being “up to code” means more than simply having lead aprons on the wall. Regulatory agencies and accrediting bodies expect facilities to:

• Maintain proper lead equivalency for each apron

• Inspect aprons for cracks, tears, and shielding breakdown

• Remove and replace damaged or non-compliant aprons

• Keep documentation of inspections and testing

• Provide proper sizing and coverage for staff

Even small defects — invisible from the outside — can significantly reduce radiation protection.

Why Lead Aprons Fail Over Time

Lead aprons are exposed to constant bending, folding, hanging, and repeated use. Over time this causes:

• Cracking of the lead core

• Breakdown of seams and overlaps

• Weight shifts that leave areas unprotected

• Wear that compromises shielding

Without regular inspection, many facilities are unknowingly relying on aprons that no longer provide full protection.

What Should Be Part of a Radiation Protection Audit?

A proper audit looks at more than just quantity. It evaluates quality, condition, and compliance. Key elements include:

• Visual and fluoroscopic apron inspection

• Verification of lead equivalency levels

• Coverage for different body types and roles

• Proper storage and handling practices

• Replacement schedules for aging inventory

This is where expertise matters.
