Medical Isotope Generators Are Essential for Nuclear Medicine Market

In the nuclear medicine market medical isotope generators are used to produce many regular used imaging isotopes. Gallium-68 and Technetium-99 generators are extremely radioactive and need to provide shielding, which is generally composed of either lead or tungsten. Without proper shielding these radioactive generators cannot be shipped or used in their applications.

Which Metals Are The Best Shielding Solutions

Radioactive generators require shielding, which is usually composed of either lead, tungsten or a combination of both metals to provide the best shielding solutions.

Tungsten, Lead or a Combination?

  • Density wise, tungsten has a higher density than lead. Lead has a density of 11.34 g/cc; tungsten has a density of 17.3 g/cc.
  • The cost of tungsten is around 25 times the price of lead because of the material difference and the processing needed.
  • Tungsten is a tougher shield than lead.
  • A hybrid or a combination of both the metals along with some other materials is the best option, as they prove to be more functional and produce cost effective results.

Counterweights are required in many types of equipment to allow the system to work properly. They can be simple steel plates or can be designed with complex geometrics because of the compartments in which they need to be placed. There are many factors that need to be considered when you are designing a product that requires counterweights.

  • How much counterweight will you need?
  • Is the counterweight going to be a freestanding part or will it be inside a compartment as one assembly?
  • How much space does the application have?
  • Are there benefits to reduce the space or size of the counterweight?
  • What are the mechanical properties needed of the counterweight and what environment is it going into?
  • Are there benefits to add more weight to the counterweight compartment?
  • Will the counterweight(s) need to be removed or will trim balancing be needed?

Counterweight Options

There are many options for counterweight designs in geometry and material. Although steel is a good option, in many instances it alone cannot attain the goals, so other metals such as lead must be used. Lead is 31% more dense than steel.

Lead Counterweights- A Good Option

Since lead melts at a relatively low temperature, it allows for steel shells or other components to be filled. It can also be cast into shapes that allow it to be poured into a tool providing a lead weight that can be installed into a specific geometry. Lead counterweights can be powder coated or painted to cover the lead for handling purposes.

Counterweight Applications

Counterweights are used in:

  • Medical equipment
  • Bridge counterweights
  • Aerospace
  • Rotating products
  • Industrial applications
  • Fork Trucks & Lifts
  • Bridge Weights
  • Elevator Weights
  • Sonar Weights

The Process of Recycling Lead

Lead is a mineral that has been in use for at least 5000 years. According to the ILA (International Lead Association) in 2013, global secondary lead production was 6.1 million tonnes. It is one of the most effectively recycled materials in the world and today more lead is produced than is mined.

Lead-based products are easily identifiable, and economic to collect and recycle due to its fundamental properties. It is malleable and corrosion resistant. And it is incredibly dense making it excellent for protection against radiation. Lead is imperative to people working in hospitals, dental surgeries, laboratories and nuclear installations. The main application for lead metal are lead-acid batteries, which is the world’s most recycled consumer product.

The ILA states, “Lead-based batteries account for more than 80% of present day worldwide lead usage and have an extremely high rate of recycling—in Europe and USA the recycling rate is greater than 95%.” Recycling centers that operate under strict environmental regulations receive used lead-acid batteries (ULAB) from countries all over the world.

Before being sent to the collection points, ULAB are returned to car accessory dealerships, car workshops, recycling businesses, DIY stores and metal dealerships. Specialized companies pick up the batteries, which are safely transported and delivered to secondary smelting plants.

The components—lead metal, paste, plastics and electrolyte (acid)— of the batteries are broken down and separated. It is then smelted and refined. The refined lead produced is either used to make new batteries or to make other lead products such as those employed in building construction, cable sheathing and in healthcare as radiation shielding.

It is far more efficient to recycle than it is to produce lead from mining, and lead recycling saves energy and reduces carbon emissions. Medi-Ray understands the importance of recycling lead and that is why we provide our customers the ability to recycle the lead products we produce for them. Thirty years ago Medi-Ray developed this environmentally sound capability which has made Medi-Ray a leader in ecologically compliant operations which safeguard the public, guarantee the proper handling of used lead products, and is cost effective for customers.

How to Protect Yourself from Radiation

With the increase in nuclear energy used in industrial development, and research and technology, the danger of exposure to radiation is a concern. Due to its life span and the ability to sustain, radioactive ions cannot be completely destroyed. As such treatment or cure due to exposure is almost an impossible task. The only way to treat radioactive exposure is through protective measures and some medicines. Mentioned below are a few measures one can adopt to minimize the effect of radioactive exposure.

Time: Exposure to radiation can be minimized by reducing the time spent near the source or substances.

Distance: Keeping distance from the radioactive source is a simple way to minimize the effect of exposure. Instead of handling a radioactive source with the hands, it is advisable to use forceps.

Shielding: Radiation shielding usually refers to shielding of bodily tissues against the penetration of radioactive rays. These shields are often termed as biological shields, as they provide a barrier between the radioactive source and the human body. It is a mass of absorbing material placed around the radioactive source or a reactor to minimize the radiation level. In order to prevent radiation, it is necessary that the absorbing materials are built and placed as per industry compliance and measures. Using a “lead glass screen” and wearing “lead aprons” is another safe way to prevent exposure.

Medicines: Potassium Iodide (KI) and Prophylaxis are medicines to combat sickness due to radiation exposure. Potassium Iodide (KI) tablets are commonly kept in stock in nuclear power plants for rapid distribution. Potassium Iodide (KI) and Prophylaxis are easily available in any pharmacy and can be taken as per the dosage prescribed by a doctor. It is advised to take the medicine within three hours of exposure to radiation for better effect; however one may take within 10 hrs, but it can be less effective.

Managing Radioactive Materials & Waste

Any activity that produces or uses radioactive materials generates radioactive waste. Mining, nuclear power generation, and various processes in industry, defense, medicine, and scientific research produce by products that include radioactive waste. Radioactive waste can be in gas, liquid or solid form, and its level of radioactivity can vary. The waste can remain radioactive for a few hours or several months or even hundreds of thousands of years.
