Why is Lead the Best Material for Radiation Protection?

One of the most important components of x-ray and radiation treatment is the prevention of harmful rays into surrounding hallways and rooms. Lead prevents the penetration of dangerous rays and is one of the best materials for radiation protection for several reasons, including its:

Density: Lead is denser than other materials, which makes it difficult for radiation to penetrate. The atomic structure in lead is packed more tightly than in other materials. This gives lead a high amount of mass and makes it more difficult for even the tiniest bit of radiation to pass through. Because of its density, lead can be used in various high-energy applications for radiation, including gamma rays, x-rays and other types of nuclear radiation.

Cost-effectiveness: A few materials, such as gold and platinum, have a greater density than lead. However, they are very expensive. Lead is another material that is dense but provides enough protection for lead shielding.

Ease to work with: One of the greatest properties of lead is that it is easy to work with. Lead performs extremely well in all types of shielding applications.

Reputation as a valued and trusted material: Because lead possesses specific characteristics such as its thickness, weight, ease to work with, resistance to radiation damage, shielding permanence and uniformity capacity, it is one of the most valued and trusted of all materials used for shielding.

What Is Nuclear Medicine and How Does It Work?

Nuclear medicine is a medical specialty where small amounts of radioactive material are used to diagnose diseases. It is non-invasive, cost-effective and can provide details about the functioning of an organ as well as the viability of the organ structure. It allows for the diagnosis of certain medical conditions and diseases much earlier than other techniques. Nuclear medicine is a great tool for the early detection, treatment and prevention of brain tumors, stroke evaluation, blood cell disorders, breast cancer, heart disease, kidney function and thyroid function.

How Does Nuclear Medicine Work?

Nuclear medicine works by introducing a low-level radioactive chemical called a radiotracer into the body. The radiotracer travels through the area being examined and emits a gamma ray signal that is picked up and read by a gamma camera. “Hot spots” show a larger accumulation of radiotracer which indicates increased activity. “Cold spots” demonstrate reduced activity.

Nuclear medicine is capable of providing information that other imaging techniques may miss. Nuclear medicine is safe because the level of radiation involved in the procedure is typically much lower than the radiation received from a conventional X-ray. Nuclear medicine procedures are painless and have no side effects.

Radiation Shielding Requirements

radiation source shielding

The most basic shielding requirements for radiation protection are dependent upon several factors including the type of radiation, exposure length and distance from the source of the radiation. Different kinds of radiation are emitted with different levels of energy. The greater the energy, the greater the level of shielding to safely guard against it. Alpha radiation is very weak, and the outermost layer of skin is enough to protect against it. Beta radiation requires more protection, such as heavy clothing. However, some beta radiation particles can penetrate and burn the skin. Gamma radiation and x-ray radiation are much stronger and require thick, dense shielding with materials such as lead.

The briefest exposure to gamma and x-ray radiation can be extremely hazardous to the human body. Even extended indirect exposure, such as an x-ray technician in a separate but nearby room close to the x-ray source, requires shielding. For medical and dental patients, the length of direct exposure to x-rays is so brief that a lead vest is all that is necessary.

Radiation is a very serious concern in nuclear power plants, industrial and medical x-ray systems, radioisotope projects, particle accelerator work and other sites. Containing radiation and preventing it from causing harm to employees is a vital part of operating equipment that emits hazardous rays. For Medi-Ray, Inc., preserving human safety and structural material that can be compromised by radiation exposure are over-riding concerns, as well as shielding sensitive materials such as electronic devices and photographic film.

Regulating the effects and degree of penetration of radioactive rays varies according to the type of radiation involved. Indirectly ionizing radiation such as neutrons, gamma rays and x-rays, is a separate category from directly ionizing radiation, which involves charged particles. Different materials are better for different types of radiation and is determined by the interaction between specific particles and the properties of the shielding materials.

Nuclear Medicine Applications

Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. It is referred to as ‘endoradiology’ because it records radiation emitting from within the body rather than radiation that is generated by an external source, such as an x-ray. Diagnostic nuclear medicine scans are different from radiologic scans because they show the physiological function of the system as opposed to traditional anatomical imaging such as a CT or MRI. In nuclear medicine imaging, radiopharmaceuticals are taken internally, intravenously or orally. External detectors capture and form images from the emitted radiation. Single photon emission computed tomography (SPECT) and positron emission topography (PET) scans are the two most common imaging modalities in nuclear medicine.

There are some practical concerns in nuclear imaging. Because the risks of low-level radiation are not completely understood, a cautious approach has been universally adopted. All human radiation exposures should be kept at As Low as Reasonably Practicable (ALARP).

According to this principle, before a patient is exposed to radiation through a nuclear medicine examination, the benefits of the examination must be identified. The particular circumstances of the patient must be considered. For example, if the patient cannot tolerate a sufficient amount of the procedure to achieve a diagnosis, it would be inappropriate to proceed with injecting the patient with the radioactive tracer. If the benefits from the procedure justify its use, the radiation exposure to the patient should be kept as low as is reasonably practicable. The images produced in nuclear medicine should never be better than required for a confident diagnosis. Giving larger radiation doses can reduce the noise in an image and make it more photographically appealing, but if the diagnostic questions can be answered without that level of detail, it is inappropriate to increase the radiation dosage.

The radiation dose from nuclear medicine imaging varies depending upon the type of study. An effective radiation dose can be lower than, comparable to, or far exceed the general day-to-day environmental background radiation dose. It can also be less than, in the same range, or higher than the radiation dose from a CT scan on the abdomen area or the pelvis. Some nuclear medicine procedures require that patients prepare before the study to obtain the most accurate results. This preparation may include dietary restrictions or the withholding of certain medications.

Some Common Myths About Radiation

Many of us have had X-Rays taken in hospitals, emergency clinics or doctors’ and dentists’ offices. Radiology, which is the science of X-Rays and high-energy radiation, is extremely important in the diagnosis and treatment of many diseases and health conditions. However, there continues to be some common myths about the dangers and risks as it relates to radiation that can be dispelled with the correct information.

Myth: Any exposure to radiation is not safe and will cause side effects.

Reality: People are continuously exposed to radiation everyday while eating food and breathing air. A study by the UN Scientific Committee showed that the risk associated with low-dose radiation is very small. During X-Rays, MRIs and other scans, the small amount of radiation an individual is exposed to will not cause side effects.

Myth: Pregnant women should not have radiology scans.

Reality: There is no evidentiary proof that a fetus is physically harmed from an ultrasound. A 3D scanner does not use stronger sound waves or produce more heat than a 2D scan, so it is equally as safe for infants.

Myth: Radiation treatment causes cancer.

Reality: The chances of getting cancer from radiation treatment is extremely small and depends on the person’s age at the time of treatment, the area of the body that is being treated and the dosage.

Radiation Facts

The two basic types of radiation are ionizing radiation and non-ionizing radiation. Non-ionizing radiation refers to a series of oscillating energy waves composed of electric and magnetic fields that travel at the speed of light. Examples are the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF) and extremely low frequency (ELF). Non-ionizing radiation is found in a wide range of occupational settings and may pose a health risk to exposed workers if not properly controlled. The six basic sources of this type of radiation are:

  • Extremely Low Frequency Radiation (ELF): This is produced by power lines, electrical wiring and electrical equipment. Intense exposure sources are induction furnaces and high-voltage power lines.
  • Radiofrequency and Microwave Radiation: Microwave radiation (MW) is absorbed near the skin and radiofrequency radiation (RF) can be absorbed throughout the body. At high intensities, both can damage tissues in the body through heating. RF and MW radiation sources are radio emitters and cell phones.
  • Infrared Radiation: Your eyes and skin absorb infrared radiation (IR) as heat. Sources of IR radiation include furnaces, heat lamps and IR lasers.
  • Visible Light Radiation: Different frequencies of the electromagnetic (EM) spectrum are seen as different colors. Having sufficient lighting is important but excessive visible radiation can damage the eyes and skin.
  • Ultraviolet Radiation: Ultraviolet Radiation (UV) is very hazardous because there are no immediate symptoms of excessive exposure. Some sources of UV radiation are the sun, black lights, welding arcs and UV lasers.
  • Laser Hazards: Lasers typically emit optical (UV, visible light, IR) radiations and can be hazardous to the skin and eyes. Some common lasers are CO2, IR laser, helium-neon, neodymium, YAG and ruby visible lasers, and the Nitrogen UV laser.

Ionizing radiation sources can be found at healthcare facilities, nuclear reactors, nuclear weapon production facilities and research institutions. These radiation sources can pose a considerable health risk to workers if not properly controlled. This is a type of energy released by atoms in the form of electromagnetic waves. People are exposed to natural sources of ionizing radiation in the soil, water, vegetation, x-rays, medical devices and other beneficial applications. Acute health effects such as skin burns or acute radiation syndrome can occur when specific radiation levels are exceeded. Long term effects of ionizing radiation can increase the risk of cancer.
