X-Ray Shielding: Medical Radiation Protection

Radiation Protection, otherwise known as radiological protection, is the science and practice of protecting people and the environment from the harmful effects of Ionizing Radiation. Ionizing radiation is used in many aspects of industry and medicine, and as a result can present significant health hazards. Such radiation causes microscopic damage to body tissue, which can lead to skin burns and radiation sickness at high exposures, as well as heightened risks of Cancer at low exposures.

Radiation protection is divided into a number of different categories, as there are many different factors to consider when it comes to protecting individuals from radiation, as well as keeping their surrounding environments radiation free.

Radiation exposure is managed by a combination of three factors, these being time, distance, and shielding. Time refers to reducing the amount of time that individuals spend exposed to radiation equipment, while still ensuring that patients receive their appropriated dosage. Distance, refers to increasing the distance between radioactive equipment, and the individuals surrounding it. Finally, shielding refers to absorbing material placed around radioactive sources, to reduce the amount of radiation to a level that is safe for humans. Types of shielding may include lead sheets in the walls surrounding an x-ray room, lead glass or screens on the viewing room for operator safety, and lead aprons for patients to wear. The effectiveness of such shields depends on shield thickness.

Mediray has developed clinic, laboratory, and medical office products for various types of x-ray applications, using such materials as lead castings, sheet lead, and lead foil.

Nuclear Medicine

Nuclear Medicine is a medical specialty, involving the application of radioactive substances in the diagnosis and treatment of diseases. In nuclear medicine procedures, radionuclides are either combined with other elements to form chemical compounds, or they are combined with pharmaceutical compounds to form radiopharmaceuticals.

When administered to patients, radiopharmaceuticals can localize to specific organs or cells throughout the body, to create an image of the extent of disease processes in the body. Nuclear medicine studies are able to identify many medical problems at much earlier stages than many other types of diagnostic tests, as it records radiation being emitted from inside the body.

Mediray takes the advancements in Nuclear Medicine and its technology very seriously. Since the company’s inception in 1970, they have focused a great deal of effort on inventions and improvements of many specialized products and services in the field of nuclear medicine, most importantly its laboratory equipment and apparatuses.

Aeronautical Lead Counterweights

Counterweights come in many different sizes, shapes, and materials, and in accordance, are used for many different things. However, the most important need for a counterweight is to create a sense of balance. In terms of Aeronautical Counterweights, their use is to keep airplane pilots from over exhausting their aircrafts.

Aeronautics is the science involved with the study, design, and manufacturing of air flight capable machines, or the techniques of operating aircraft and rocketry within the atmosphere. Counterweights used in this regard, are also known as bob weights. Their main purpose is to change the amount of control force required to deflect an airplane’s control column. This process is dependent on the factor of air speed.


By installing lead counterweights into aircrafts, aeronautical engineers can make it more difficult to pull on the control column as g-force increases. G-force is the force to which a body is subjected when accelerated. The installation of lead counterweights in aircrafts is an important safety procedure, as it ensures that a pilot will not overstress his aircraft.

Medi-RayTM‘s skilled team of craftsmen pride themselves on the production of such counterweights, as well as many others with a wide range of sizes, material types, and uses.
