Executive summary
The present document provides information about applications and technical background of Nuclear Magnetic
Resonance (NMR) systems. The current frequency regulation is shown. A request for clarification for allocation and
regulation of NMR devices is placed.
Introduction
Nuclear Magnetic Resonance (NMR) systems are applicable for a huge spectrum of applications. For NMR systems in
focus of the present document, neither the frequency regulation is clear, nor are frequency allocations available for a
wide range of NMR applications.

1 Scope
The present document provides information on NMR systems operating in the frequency range below 130 MHz.
It deals only with NMR systems using earth magnetic field strength of rare earth magnets and electromagnets and not
with superconducting magnets. This limits the maximum static magnetic field strength to less than 3 Tesla. As a direct
result, the maximum proton nuclear magnetic resonance is limited to less than 130 MHz. The minimum nuclear
resonances of nuclei in scope are below 1 kHz in earth magnetic field.
There are two types of NMR devices:
1) "enclosed NMR sensor": Material under Test is put inside the device;
2) "open NMR sensor":
- material under Test is placed on the device;
- opened to one side for measurement of building materials like a GPR or WPR generating wanted field
emission at the sensor boundaries;
- opened 360°, e.g. like a pole inside a Material under Test generating wanted field emission at the sensor
boundaries;
- there is no enclosure around the sensor, called "open NMR sensor".
Only "enclosed NMR" sensors" are in the scope of the present document.
Nuclear Magnetic Resonance Imaging (MRI) and Magnetic Resonance Tomography (MRT) systems are out of scope.
It reviews the present regulations for NMR systems (if any), the related markets and the evolution of the technology and
it identifies limits for NMR systems operating below 130 MHz.
The present document contains the necessary information to support the possible co-existence and compatibility studies
to be conducted by the CEPT/ECC, including:
• market information;
• technical information;
• regulatory issues.
