Ionizing radiation & NORM division
Independent radiation and NORM testing, anywhere in Florida
A separate division from our EMF work, with a separate instrument and a separate method. We survey properties, items, stone and facilities for ionizing radiation and naturally occurring radioactive material, and hand you a documented reading set — on your timeline, without waiting in a government queue.

Two different things with similar names
EMF/RF versus ionizing radiation and NORM
| EMF / RF (non-ionizing) | Ionizing radiation & NORM | |
|---|---|---|
| What it is | Non-ionizing electromagnetic fields — magnetic, electric and radio frequency energy. | Ionizing radiation — alpha, beta and gamma emissions with enough energy to strip electrons from atoms. |
| Typical sources | House wiring, panels, smart meters, cell towers, Wi-Fi, solar inverters, EV chargers. | Naturally occurring uranium, thorium and radium in soil, rock, phosphate ore, natural stone, and in some antiques and industrial devices. |
| How it is measured | Three-axis field meters reading milligauss, volts per metre and microwatts per square metre. | A Geiger-Mueller pancake-probe survey meter reading count rate against local background. |
| What we report | Readings by room and source, compared against published guideline values. | Readings against your own site background, with a confirmed hot-spot map. |
| Where to start | A whole-home EMF inspection. | A gamma radiation baseline survey, or item screening for a collection. |

The instrument
Radiation Alert Ranger
Every survey is performed with a Radiation Alert Ranger — an industry-standard Geiger-Mueller pancake-probe survey meter used for alpha, beta, gamma and X-ray detection. The wide pancake window is what makes surface hot-spot work practical rather than approximate.
Calibrated weekly against a check source, with the date recorded on every report.

Three steps, no surprises
Book a consultation
Tell us the property, the item, or the facility and what prompted the call. We confirm scope, price and the travel zone in writing before anything is scheduled.
On-site survey with our calibrated instrument
We survey with the Radiation Alert Ranger, taking a local background reference first, then working the area to a fixed pattern so nothing is sampled by chance.
Receive your written report
A written report with the hot-spot map, every recorded reading against your own site background, photographs, and the instrument calibration date. Typically within 48 hours.
Methodology
How we survey — the actual method
Background reference first
Before anything else we record ambient background at the property line. Every later reading is reported against that number, because a reading only means something relative to local background.
Fixed-pattern coverage, not spot checks
Interior areas are walked room by room at a steady pace with the probe held at a consistent height. Yards and lots are walked on a grid — roughly 15-foot lanes on a typical residential lot, tightened where the meter responds.
Hot-spot confirmation
Anywhere the count rate rises above the site background, we stop, tighten the search, and take timed readings at the peak. A location is only recorded as a hot spot after it repeats on a second pass.
Priority zones get extra time
Bedrooms, children's play areas, garden beds, home offices and any spot where someone spends hours at a time are surveyed more densely than pass-through space.
Everything is documented
Each recorded reading is logged with its location, the value, the time, and the instrument calibration date, then plotted onto a floor plan and lot sketch in the report.
Who performs the survey and how we work
Surveys are performed by the owner-operator of EMF Testing Services, trained in survey-meter operation and in the survey procedure described on this page, working to the same written methodology on every job.
We hold no regulatory role and claim no agency standing. What we provide is a documented instrument reading set: where the meter was placed, what it read, when the instrument was last calibrated, and how those readings compare to the background level measured at your own property on the same day.
Common questions
What is the difference between EMF testing and radiation testing?
EMF testing measures non-ionizing fields from wiring, power lines, towers and electronics. Radiation testing measures ionizing radiation and naturally occurring radioactive material — uranium, radium and the gamma emissions from their decay — which requires a completely different instrument.
How much does radiation testing cost in Florida?
A full gamma radiation property survey is $449 flat, including the hot-spot map and written report. Item, countertop and industrial screening are priced separately, and travel is included within 25 miles of Tampa with flat zone fees statewide.
What instrument do you use?
A Radiation Alert Ranger, an industry-standard Geiger-Mueller pancake-probe survey meter used for alpha, beta, gamma and X-ray detection. It is calibrated weekly against a check source, and the calibration date appears on every report.
Do your surveys satisfy a government requirement?
No. Our surveys are independent, informational measurements for personal due diligence, negotiation and peace of mind. They are not represented as satisfying any specific agency's statutory testing or survey requirement.
Do you serve all of Florida?
Yes. We are based in Tampa and travel statewide, with travel included within 25 miles, a flat $99 zone out to 100 miles, and $199 beyond that. Item screening can also be handled by mail.

Quoted in writing before you book — never added afterward.
Our radiation surveys are independent, informational measurements performed for personal due diligence. They are not represented as satisfying, replacing or substituting for any specific government agency's statutory testing, survey or disclosure requirement, and they are not a medical or health assessment.
Get a documented reading, not a rumour.
One all-inclusive price: $399 for a complete EMF inspection of any size home. That covers every test, every room, and the written report — no square-footage tiers. Flat travel zones apply outside Hillsborough County; we serve the entire state of Florida.
