Radon causes approximately 21,000 lung cancer deaths every year in the United States. It is the second leading cause of lung cancer overall, and the number one cause among non-smokers.

What is high: The U.S. Environmental Protection Agency recommends taking action if indoor radon levels are 4 picocuries per liter (pCi/L) or higher. Many experts also suggest reducing levels between 2 and 4 pCi/L when feasible.
Radon: Has no smell, color or taste.
The main health risk from radon is lung cancer. Increased lung cancer risk: When radon gas is inhaled, radioactive particles can become trapped in the lungs and damage lung tissue over time.
No immediate symptoms: Radon exposure does not usually cause noticeable short-term symptoms, so people can be exposed for years without realizing it.
Long-term exposure matters most: Risk increases with both the radon concentration and the length of time spent in the environment.
Why We Have Both a Radon Scan and a Radon Test
Our radon scan is included with every home inspection and serves as a preliminary screening for the presence of radon. Our radon test is a more in-depth evaluation that uses a 48-hour continuous radon monitor to provide more comprehensive and accurate results. We use top-of-the-line equipment that contains six built-in radon sensors and is regularly sent out for calibration to ensure accuracy.
Our radon testing process follows EPA guidelines, providing reliable results to help you make informed decisions about your home and your health.
Exposure to elevated sources can have various biological effects ranging from subtle increases in long-term cancer risk to acute, severe illness if high radiation thresholds are breached .

Common radiation sources inside and outside your home include:
Building Materials: Granite, brick, and concrete contain trace amounts of uranium and thorium, these emit low levels of gamma radiation.
Drinking Water: Private wells and public water systems can contain dissolved natural radionuclides like radium.
Household Items: Smoke detectors and antique glassware contain very small amounts of radioactive isotopes.
Electronics: Microwave ovens, Wi-Fi routers, and televisions emit non-ionizing radiation.
Cosmic Rays: The earth is continually bombarded by energy from space, which naturally increases depending on your geographic altitude.

1. Thermal Effects (Heating) Tissue Burns: Absorbed RF energy raises body tissue temperature, which can lead to deep, severe skin burns. Eye Damage: The eyes lack adequate blood flow to dissipate heat, making them highly susceptible to cataracts at high exposure levels. Heat Stress: The body's core temperature can rise, leading to heat exhaustion, fatigue, and systemic stress.
2. Neurological and Behavioral Effects Nerve Stimulation: Rapidly changing electrical and magnetic fields can trigger nervous structures, resulting in uncomfortable electrical shocks or involuntary muscle contractions. Auditory Perception: Very short, intense pulses of microwave RF can be perceived by the brain as clicking or buzzing sounds, known as the "microwave hearing effect".
Neurasthenic Symptoms: Individuals exposed to high, yet sub-thermal levels of RF (such as engineers working close to antennas) sometimes report symptoms like headaches, dizziness, fatigue, and memory issues.
3. Cellular and Systemic Effects Oxidative Stress: Experimental models suggest that intense RF exposure can cause an increase in the production of free radicals, which may lead to cellular damage and inflammation. Ion Channel Alteration: Research indicates RF might interfere with the function of ion channels in cellular membranes, potentially altering normal cellular processes.
Cancer Risk: Unlike ionizing radiation (like X-rays), RF does not directly damage DNA.
However, global health organizations classify RF-EMF as "possibly carcinogenic to humans,"
though evidence remains debated and inconclusive for everyday exposure levels.
Documented High-EMF Health Effects Short-term acute effects (usually only at high exposure thresholds):
Tissue Heating: High-frequency radio waves cause water molecules in the skin and tissues to vibrate, generating heat.
Nerve Stimulation: Strong low-frequency magnetic and electric fields can induce currents in the body, causing muscle contractions or tingling sensations.
Sensory Disturbances: Intense fields can stimulate the retina, causing you to see flashing lights (magnetophosphenes).
Shocks and Burns: Touching conductive materials in strong EMF fields can cause perceptible shocks or thermal burns. Long-term or low-level biological effects (subject of ongoing research):
Oxidative Stress: Exposure may increase free radicals and alter antioxidant markers in the blood. Sleep and Headaches: Some studies link chronic, heavy exposure to persistent headaches, fatigue, and sleep disturbances.
Cardiovascular Changes: Research suggests acute exposure can temporarily alter heart rate variability. Electromagnetic Hypersensitivity (EHS): Some users report symptoms like skin burning, dizziness, and cognitive difficulties, though health organizations generally categorize this as medically unexplained.

Thermal scans (infrared thermography) are used in home inspections to identify hidden, non-visible defects. By detecting surface temperature variations, they pinpoint hidden moisture from leaks, missing or damaged insulation, air drafts, and overheating electrical components that standard visual inspections miss.
A professional inspector will use thermal imaging for several primary applications: But, in the hands of an untrained inspectors you will get a lot of false and alarming information, make sure your inspector is certified in thermal imaging or better yet make sure he is an actual Thermographer.
1. Detecting Hidden Moisture and Roof Leaks How it works: Water and moisture absorb and conduct heat differently than dry building materials, creating distinctly cooler signatures.
What it finds: Inspectors can spot roof leaks, plumbing pipe drips, or water intrusion behind drywall and floorboards long before visible mold or water stains appear on the surface.
2. Identifying Energy Loss and Insulation Gaps How it works: Areas with missing or improperly installed insulation allow cold or warm air to bypass the home's thermal envelope.
What it finds: The camera visualizes these drafts and insulation voids (often in ceilings and exterior walls), highlighting exactly where a home is losing energy, which helps improve overall efficiency.
3. Finding Electrical Hazards How it works: Overloaded circuits, loose wiring, and failing components generate abnormal friction and resistance, which show up as intense, bright "hot spots" on the infrared screen.
What it finds: It acts as an early-warning system for potential fire hazards hidden inside walls or behind electrical panels.
4. Spotting Plumbing or HVAC Issues How it works: By scanning radiant heating lines, ductwork, and registers, inspectors can quickly determine if HVAC systems are operating properly.
What it finds: Blocked ducts, leaking radiant floors, or failing equipment often display as abnormal temperature drops or spikes.
Why the Context Matters (Especially in N.C.) In humid or storm-prone areas—like Central and the broader North Carolina region—identifying hidden moisture early is vital for preventing wood rot and costly structural repairs. If you are planning to buy or sell a home, an infrared scan is an excellent non-invasive layer of due diligence.
In home inspections, UV (ultraviolet) light is used to spot hidden biological and chemical hazards that are invisible to the naked eye.
Common uses for Ultraviolet light during an inspection include:
Mold Detection: Mold spores and fungal growths fluoresce (often glowing bright white, yellow, or green) under UV light. Inspectors use this to find hidden mold on HVAC coils, ceiling rafters, and drywall.
Plumbing Leaks & Water Damage: Certain minerals in tap water or specific leaks fluoresce, making it easier to trace the origin of water stains and moisture issues.
Pest and Rodent Activity: Rodent urine trails glow brightly under UV light. Inspectors scan basements, attics, and baseboards to identify active pest infestations.
HVAC Refrigerant Tracing: Technicians and inspectors add UV-reactive tracer dye to AC systems to easily pinpoint small, hard-to-find refrigerant leaks.
Most serious effects of mold exposure: Neurological and Cognitive Issues
Brain fog: Leads to memory problems and cognitive impairment.
Constant headaches: Causes persistent, severe head pain.
Mood changes: Triggers chronic fatigue, anxiety, and depression.
The worst effects of mold include severe respiratory distress, invasive fungal infections, and chronic neurological issues. These effects target your lungs, nervous system, and overall immunity. Vulnerable populations face the highest risk of long-term or life-threatening complications

Common effects of mold exposure: Allergic reactions. Many people experience allergy-like symptoms, including: sneezing, runny or stuffy nose, itchy eyes, nose, or throat, watery eyes, and skin rash.
Respiratory symptoms. Mold can irritate the airways and may cause: coughing, wheezing, shortness of breath, chest tightness, and sore throat. For people with asthma, mold exposure can trigger asthma attacks or worsen symptoms.
Sinus and nasal problems. Prolonged exposure may contribute to: chronic nasal congestion, recurrent sinus irritation, and headaches related to sinus inflammation.

Radon and radiation are related, but they are not the same thing.
A simple analogy:
The bulb (radon) produces the light (radiation), but they are different things.
There are also different types of radiation:
Summary:
Radon is a specific radioactive substance, while radiation is the energy emitted by radioactive substances (including radon) and many other sources.
