ScanTech Technical Consulting has had experience in performing EMF testing and EMI surveys for the following manufacturers of implanted biomedical devices:
- Boston Scientific
- Abbott Laboratories / St. Jude Medical
- Tandem Diabetes Care
While newer generation designs tend to be more resistant to external influences, I still routinely find sources of EMF interference that exceed the manufacturer specifications, particularly in work and industrial environments. (but residences are not exempt for reasons discussed below)
This is due to a number of reasons:
1) Our electromagnetic spectrum is more crowded than ever and we are constantly adding new electronic devices and spectral intensity to our everyday environment. Examples include:
- Wireless phone chargers
- Battery chargers for electric vehicles & power tools
- WiFi, Wireless Internet and Bluetooth
- Hybrid Electric Vehicles (HEVs)
- Wireless microphones and media systems
- Smartphones – cell phones, cordless phones (particularly those with inductive charging)
- Security scanners for weapons detection
- RFID (Radio Frequency Identification) reader systems for entry control
- Portable music devices, Bluetooth Speakers, headphones for iPods and MP3 players
- Laptops, tablets, desktop computer power supplies
- Electric scooters, drones, hybrid & electric vehicles including scooters, utility vehicles, golf carts, Segways, Gators, etc.
- Internet access points, wireless repeaters, amplifier boosters and cellular phone boosters (AWS or Advanced Wireless Systems in the 1.7 GHz range)
2) Many industrial and manufacturing environments have equipment which emits and broadcasts EMFs at relatively high power levels over a broad range of frequencies:
- Electric welding equipment (MIG, TIG, SMAW, etc.) and welders
- Corded and cordless power tools
- Generators, alternators, fan & cooling motors
- RF clam shell sealers
- Semiconductor fabrication plant equipment assets
- UPS (Uninterruptible Power Supply) banks & DC battery backups
- Cleanrooms / semiconductor fabrication equipment
- MCC (Motor Control Centers) Switchgear Rooms and VFD (Variable Frequency Drive) motor drives for AC / DC
- AC and DC motors found in blower motors / fans, HVAC equipment, pumps
- Walkie-talkie base stations & 2 Way Radio Microphones
- Apple iPhones and other phones that use Inductive Charging technology
- Induction furnaces
- High powered DC Rectifier arrays
- Transformers, medium & high voltage power lines & substations
- Industrial electromagnets & jig fixture permanent magnets
- High powered industrial CO2 (Carbon Dioxide) and YAG fiber optic lasers in the kW (kiloWatt) range
- Magnetized structural beams
- Electrochemical manufacturing cell rooms and buildings
3) Some facilities have entire areas that are flooded with electromagnetic energy such as:
- Electric substation yards
- Electrical Welding Areas (MIG, TIG, SMAW, Arc, etc.)
- Manufacturing facilities with inductive heaters
- Large DC rectifiers carrying heavy current
- RF Clamshell sealers at 13.56 MHz or 27.12 MHz
- MCC (Motor Control Center) rooms with 4160 V & 480 V switchgear panels and power feeds
- Transformers in switchgear rooms
- High current wires not shielded by metal conduit
- VFD – Variable Frequency Drives (AC) and VSD – Variable Speed Drives (AC & DC power)
- Incorrectly wired infrastructure which can set up unexpected fields in a large area
- Chemical cell rooms (found in agrochemical, alkali chemical production facilities)
- Cellular / microwave towers 3G, 4G, 5G, LTE (Long-Term Evolution) and other RF equipment on tall building rooftops
- MRI Rooms in hospital and medical facilities
and so forth can all cause malfunctions and intermittent operation in nearby mission critical electronics. Significant DC magnetization has even been found in the structural metal of buildings and in ferrous alloy stock.
4) There are environments which may have unexpected sources of high magnetic fields. I once did a survey of an exhibit in a museum where one of the plasma display items possessed an unusually high magnetic field that was worth investigating. Hospitals and scientific research centers may have MRI (Magnetic Resonance Imaging) and NMR (Nuclear Magnetic Resonance) equipment which uses exceptionally strong DC magnets and Radio Frequencies.
5) Even in conventional office buildings you have server rooms, electrical rooms and conventional power transformers next to employee working areas. It is also not unusual for some areas to have “rogue” transmitters for personal wireless or even corporate eavesdropping devices.
The confluence of the above effects may cause unexpected performance issues in even the most sophisticated biomedical devices and equipment through either radiated near field or conducted interference.
RF & wireless interference is a common issue in many mysterious anomaly situations. Computer controlled systems can be highly susceptible to interference from both radiated and conducted sources, and this can include server rooms, A / V equipment, security systems, hospital monitoring systems, etc.
As more technologies such as WiFi, Wireless Internet, Bluetooth, RFID and other communication linked technologies began to saturate offices and manufacturing plants, the potential for conflicts only increases. An experienced consulting company such as ScanTech can help minimize downtime and frustrating delays by quickly isolating and mitigating such interference problems.
ScanTech also has experience in working with child / infant anti-abduction systems by Stanley Healthcare (HUGS) and McRoberts Security Technologies. (MyChild)
While ScanTech is based in the Dallas – Fort Worth area, we have done numerous EMF & EMI surveys for biomedical devices and bio-instrumentation in the Houston, Austin – San Antonio area and nationwide / international. (particularly Michigan and Iowa where there is a heavy industrial presence)
Biomedical imaging including X-Ray projection radiology, MRIs, (Magnetic Resonance Imaging) CT (Computed Tomography) machines, portable ultrasound and other diagnostic equipment is subject to interference from a variety of sources including the power mains, computer interface, etc. particularly since they can be operated in a variety of modes under varying environmental conditions.
ScanTech has experience in working with bio instrumentation, biomedical sensors, X-Ray equipment, portable MRIs, and taken coursework covering the fundamental physics behind nuclear medicine, radiology, ultrasound and other imaging modalities.
