Thinner hospital radiation shielding walls achievable

Using MagnaDense in the construction of wall, ceilings or floors to protect against radiation, allows for thinner constructions.

In a recent building publication the use of Minelco MagnaDense as an aggregate in concrete mixes for radiation shielding was featured.

When building radiation shielding bunkers in hospitals designers and architects experience lots of challenges. With normal concrete the walls will be very thick which increases build area hence costs. Another important aspect is the patient experience. The thicker the wall, the more unwelcoming it might feel which is a direct contradiction to what a designer is trying to create in healing environments.

Minelco offers a solution with an environmentally friendly magnetite material that increases density enabling radiation shielding wall thickness to be significantly reduced; in this case from 2.6 meters to a mere 1.65 meters. The main benefits of Minelco MagnaDense for radiation shielding are:

  • More weight - less volume – less cost
  • Concrete density of up to 4.0 t/m3
  • Up to 40% space saving
  • Patient friendly
  • DIN 6847-2 approved concrete
  • EN 12620 approved aggregates
  • Proven use for over 4 decades

In the Swedish Building Magazine “Byggfakta” MagnaDense featured in a story about the top modern build of a radiation treatment bunker for the oncology clinic at the County Hospital in Kalmar, where Minelco partnered with Swerock and HansaBygg.

Minelco delivered 1,100MT of MagnaDense 8s and MagnaDense 20s (different aggregate sizes) to Swerock AB (Swedish Ready mix concrete producer) who in turn supplied the ready mixed concrete to the constructor HansaBygg.

The magnetite was delivered by 2 trains from Kiruna to Kalmar, a distance of about 1650km (1025 miles). Besides offering delivery by train Minelco also supplies via trucks (30 MT per load) or vessels (more than 3000 MT), which puts us in a position to be able to deliver to projects of all sizes.
