Harmful Effects of X-Rays

Why X-Rays Are Harmful

X-rays are high energy electromagnetic rays, which have a strong ability to

ionize air or gas. When X-rays fall on human body they break up the

molecular bonds and produce free radicals.

These free radicals are highly reactive and disturb the proteins, which are vital

to health. Also it damages the cells and sometimes a damaged cell survives and

continues to produce more damaged cells, which results in cancer.

Important:

Even a very low dose of radiation may destroy tissue or initiate tumor

development.

Application of X-Ray Protective Products

Protection against secondary (scattered)

radiation

Products developed for personnel in the field

of radiation

Types of radiation:

- hard radiation > 100 kV (e.g. for bones, lead, plaster)

- soft radiation < 100 kV (e.g. soft tissue, breast tissue)

X-Ray Protection for Patients and Medical Staff

Radiosensitive Organs

Organs with a high cell division rate are

lymphoid organs, bone marrow, blood, testes, ovaries, intestines

Organs with fairly high radiosensitivity are

skin and other organs with epithelial cell lining (cornea, oral cavity, esophagus,

rectum, bladder, vagina, uterine cervix, ureters)

Organs with moderate radiosensitivity are

optic lens, stomach, growing cartilage, fine vasculature, growing bone

Important:

Patients are exposed to the x-ray extremely briefly, which reduces the impact of

any damage to their bodies. Medical personnel, however, is often exposed to

radiation every day for several hours.

Scattered Radiation

Where does the X-Ray Radiation Come

from?

In addition to primary radiation, there exists a

secondary or scattered radiation.

Scattered radiation originates primarily in the body of

a patient as radiation during its passage through a

substance comes out with a changed direction.

Radiation can also undergo subsequent scattering

from the walls and other objects in the examination

room.

X-Ray Protective Accessories for Eyes

Cataract Risk

Lens of the eye is very sensitive to iodizing

radiation, which can cause permanent damage

Due to that, eyes should be protected from radiation

Risk of cataracts exist

The statutory annual dose limit for eye lenses has been

150 mSv. With the recommendations of April 2011, the

IRCP (International Commission on Radiation Protection)

advised a further dramatic reduction of the limit values:

- annual exposure should not be more than 20 mSv

over a 5 year average

- no annual exposure should exceed 50 mSv

X-Ray Protective Accessories for Eyes

X-Ray Protective Eyewear

MAVIG has designed a new collection to provide a comfortable

fit for a wide range of facial shapes and sizes.

Important: It is the lenses and not the frame that protects the

eye lenses from radiation!

Glasses should sit on the cheekbones to close the space

between face and lenses to protect from radiation coming

from below

Glasses should also press against the temples to protect from

radiation coming from the sides

Glasses should be chosen by each user personally by trying

on different models

X-Ray Protective Accessories for Eyes

Strengths:

Anti-reflective coating (optional)

Pb-Value in 0.50 mm or 0.75 mm

Modern Design

Only model BR126 has side

protection
