Scatter Radiation: How to Protect Yourself in the Cath Lab

Scatter Radiation in the Cath Lab

During a typical procedure in the Cardiac Catheterization Laboratory, radiation is deflected from the patient’s body and scattered to all areas of the lab. This scatter radiation is not only associated with skin damage and eye injury, but the low-dose radiation has been shown to increase the number of circulating lymphocytes and chromosomal abnormalities, increasing one’s risk of cancer. This phenomenon has been universally recognized and extensively documented, leading to the implementation of radiation protection techniques and equipment by all medical staff working in the vicinity of the patient. Although most personnel are routinely wearing X-ray protective garments, there is evidence that the incidence of radiation-related disease in long-serving Cath Lab staff is statistically higher than in non-Cath Lab staff. In order to combat this trend, one solution suggested is to routinely place radiation-protective shields over each patient, drastically reducing the amount of scatter radiation in the lab.


The Intensity of Scatter Radiation

Despite the use of protection, research published in the American Heart Association journal shows that attending cardiologists and other staff working in positions close to the patient are exposed to radiation that, over a working career, could be the equivalent of more than 2,500 chest X-rays. Other work shows that cardiologists’ necks and heads receive radiation doses of 2 to 3 rems per year. Interestingly, the lefthand side of the head receives more radiation than the right side, indicative of positions taken by cardiologists during procedures.


Health Risks

Although the level of scatter radiation is low, there is statistical evidence that indicates interventional cardiologists have almost three times the incidence of cancer compared to unexposed staff. This view is based on work conducted by the CNR Institute of Clinical Physiology in Pisa, Italy – interviewing 466 medical personnel working in Cath Labs. Furthermore, medical staff with more than 16 years of experience in Cath Labs were eight times more likely to have cancer than those who did not. The incidence of skin lesions, orthopedic problems, and cataracts was also higher.


Conventional Protective Measures

The standard methods of protecting Cath Lab staff from radiation exposure involve techniques such as keeping the team as far from the source of radiation as possible and using equipment such as lead or composite shields, supplemented in some instances by portable radiation shields. Although these measures are effective, it is nearly impossible for cardiologists to stand far enough away from the patient unless remote robotic methods are used.


Scatter Armor Radiation Protection

Scatter radiation occurs due to the targeted beam striking objects, such as the patient’s body, and reflecting a more harmful secondary radiation in all directions. One method of reducing the medical staff’s exposure to this dangerous scatter radiation is implementing Infab’s Scatter Armor Shields.  These shields are placed on the patient’s body and positioned to block scattered radiation in all Cath Lab procedures.

Although lead has been standard in the industry for years, the weight of lead-based shielding is somewhat impractical, and other alternatives have been explored. The KIARMOR bilayer is the perfect solution to this matter. KIARMOR is made from the elements bismuth and antimony, which are combined into a single bi­layer sheet. This innovative technology not only provides you with a lighter-weight alternative, but it is also more effective than equivalent lead-based shields. KIARMOR is lead-­free, and its shielding properties are such that it meets the requirements of the three international standards (ASTM F2547-18, IEC 61331-1:­2014, and DIN 6857­1-1) covering radiation protection. In addition, each Scatter Shield has KIARMOR at its core, making these shields the most effective option in reducing the amount of one’s exposure to scatter radiation in the Cath Lab.  Visit our website  Search results for: 'scatter armor' (    to purchase your Shields today!

Have You Updated Your Radiation Glasses?

One topic that is important to our customers and to Z&Z Medical is the protection of an x-ray technologist's and a radiologist’s eyes. More than ever, our industry is acknowledging the extreme sensitivity of the human eye to radiation. After the Internal Commission of Radiological Protection announced that the threshold of acceptable radiation exposure to the eye was much lower than was previously suggested, radiology imaging professionals have expressed a greater level of concern when it comes to shielding of their eyes. Z&Z Medical provides a wide range of current up to-date glasses that are not only superior in protection but that also provide a greater level of comfort compared to older styles of the past.  

Safety is Paramount!

The very reason you're putting on radiation protection glasses is to protect your eyes from the dangers of scatter radiation and minimizing your risk for cataract development. The risk of early cataract development is a real concern for anyone working in the medical imaging environment. With our protective eyewear, you can be sure you're getting the shielding you need to be safe.  

Comfort is Key!

Z&Z Medical offers a wide array of protective glasses that are lightweight and designed to put less pressure on the bridge of the nose and on the back of the ears. A lot has changed over the years and comfort is one of them!  The glasses that are available now are very comfortable and don’t create a burden to wear them.

Got to have Style!

No more worries about glasses that look like the older outdated protective eyewear from years past. Today’s x-ray protective glasses not only give you the protection you need and the comfort you desire, but they also give you a choice of style. Sporty, smart, sleek - whatever look you desire, you can find them with Z&Z Medical.

Since the standards for eye protection has changed over the years, so too has the advancement of radiology protective eyewear . Maximum protection and comfort are right at your fingertips. If you haven’t upgraded your radiation glasses, wait no longer. Come check out Z&Z Medical’s lead glass offerings today.

Half the Apron But a Whole Lot of Protection!

There are many benefits of half aprons. They provide peace of mind to patients who are concerned with protection during imaging procedures, and they provide ease of use to radiologic technologist who use them to shield patients during imaging procedures of the upper body or upper extremities. Often used for standing chest radiographs when they are placed on the backside of the patient, they are also often used on the lap of patients when imaging extremities or pediatric patients.  While recent studies have shown little to no benefit of using this to shield the gonadal region, patients still often demand the use of shields during their exam.
