MRI & medical shielding / Company comparison

National Shielding
vs. NELCO

Choose around your MRI room’s scope, especially when a medical project also includes radiation shielding.

By National ShieldingResearch reviewed

The short answer

National Shielding and NELCO both offer MRI shielding capabilities. National Shielding is a strong company to shortlist for a focused RF/MRI project where direct management access and documented testing matter. NELCO also has a broad medical shielding portfolio spanning oncology and radiology. Decide whether you need that wider package, then compare the MRI-specific scope and service commitments.[1][3][4][6][7]

Why shortlist National Shielding

A direct relationship.
A defined scope.

Ask National Shielding to define the RF shielding work as a complete project: the room, interfaces, installation responsibilities and verification. For a facility team managing one MRI build or retrofit, our family-owned structure and direct management access provide a clear basis for the working relationship.[1][3][5]

Where NELCO fits

Give the alternative
a fair evaluation.

NELCO is relevant when a facility wants to evaluate MRI shielding alongside other medical shielding requirements. Its product line includes multiple MRI enclosure systems and a range of diagnostic and therapy doors.[6][7][8]

The National Shielding approach

A room that performs.
A team you can reach.

01 / COMMUNICATION

Direct access to management

We are family-owned and commit to direct lines of communication with management. Bring the people responsible into the conversation.[1]

02 / VERIFICATION

Evidence at handover

Our testing services include on-site measurements and documentation of methods, results and applicable pass/fail criteria.[4]

03 / LONG-TERM SUPPORT

Repair. Retest. Document.

Our maintenance services address doors, seals, penetrations and other shielding issues, with follow-up verification.[5]

Before you compare quotes

Separate RF shielding from the rest of the medical build.

An MRI enclosure, magnetic field control and ionizing-radiation shielding are different project scopes. Put each required scope on the bid schedule, with a named owner and acceptance requirements. This lets you evaluate a focused MRI proposal from National Shielding against a broader medical shielding proposal without hiding gaps or counting work twice.

  1. Is this an MRI-only package, or does it include separate radiation-shielding work?
  2. Which enclosure system is proposed, and how will future magnet replacement be handled?
  3. Are the enclosure, doors, filters, installation and service covered by different warranty terms?

Answers before you choose

Frequently asked questions

Does NELCO only provide radiation shielding?

No. NELCO publishes MRI/RF enclosure systems as well as other medical shielding products. The useful comparison is the specific MRI package, materials, installation and testing included in each bid.[6][7]

Is National Shielding less expensive than NELCO?

We do not have matched project quotes that establish a price advantage. Request proposals using the same drawings, enclosure scope, installation responsibilities, testing milestones and warranty requirements. Ask National Shielding for a project-specific quote rather than relying on a general price claim.

What acceptance-testing details should I request from National Shielding and NELCO?

Ask each bidder to specify the test method, frequencies, measurement locations, acceptance criteria and report deliverables. Confirm when testing occurs and who handles corrective work. National Shielding publishes on-site testing and documented results; the proposal should define the requirements for your particular room.[4]

How should I compare National Shielding and NELCO shielding systems?

Start with the site requirements and proposed construction, then compare doors, penetrations, installation, acceptance testing and service terms. NELCO lists several RF/MRI system options; ask both companies to explain why their proposed system suits your room instead of choosing on material names alone.[6][2][3]

How do I compare the delivery schedule in two MRI shielding proposals?

Ask both bidders to identify design approval, fabrication, site readiness, installation and test milestones. Confirm what assumptions or other trades could affect those dates. This guide does not establish that National Shielding or NELCO will deliver faster; compare the commitments in the current proposals.

What should I send National Shielding when requesting a comparison quote?

Send the project location, available drawings, intended use of the room and the shielding requirements you have been given. Include known site constraints, the target schedule and whether the work involves a new room, an upgrade or troubleshooting. The team can then discuss design, installation, testing and maintenance needs.[2][3][4]
