Safety Tips for the Holidays
November-December 2009 (Palm Springs, Calif) — CREIA, the California Real Estate Inspection Association, cares about your safety during the holiday season. The following are a few tips that can keep you and your family safe while enjoying this festive season.
Electrical Safety
Use only Underwriters Laboratories (UL) approved lights on your tree.
Avoid overloading the connections.
Do not leave Christmas tree lights on while unattended.
Check all light sets prior to use. Do not use damaged light sets or extension cords.
Make sure you have a working smoke detector on every level of your home.
Christmas Tree Safety
Keep your tree away from heat sources, sparks or flames.
Choose a freshly cut tree. LIVE TREES NEED WATER! Check and refill often.
Cut a few inches off the trunk before placing in water.
When your tree becomes dry, discard it promptly.
Avoid accidents by using wire or cord to secure your tree to the wall or ceiling (this will prevent it from toppling over by small children or pets).
Holiday Candle Safety
Do Not use candles near combustible materials such as curtains, drapes, bedding and or cabinets.
Do Not leave the house with candles burning.
Do Not leave children or pets unattended with a lit candle.
Do Not use candles on a Christmas tree.
Be sure that candles are in stable holders on a flat stable surface and create a 1-foot circle of safety surrounding them.
CREIA advises everyone to make sure to retain the services of a qualified, professional home inspector by using a Certified CREIA Inspector member to do a thorough, independent visual examination of the physical structure and systems of a home. Since 1976, CREIA, a non-profit voluntary membership organization has been providing education, training, and support services to the real estate inspection industry and to the public. Inspectors must adhere to CREIA's Code of Ethics and follow the Standards of Practice developed by the association. These Standards of Practice have been recognized by the State of California, and are considered the source for Home Inspector Standard of Care by the real estate and legal communities.
CREIA requires its members to successfully pass a comprehensive written examination of property systems and complete 30 hours of continuing education each year. Members can accumulate credits through various sources of education including monthly chapter meetings, conferences, and other approved activities. CREIA keeps records to ensure that members are complying with the requirements. Educational topics cover a variety of technical subjects including updates and advances affecting the profession of real estate inspection.

Radon Impact on Home Safety
Health Effects of Radon
By Dr. Harriet Burge, EMLab P&K Chief Aerobiologist and Director of Scientific Advisory Board
Radon is one of the "noble" gases (such as neon and argon). It is a naturally occurring element that is produced from radium which is part of the uranium decay series. Radon has a half-life of 3.82 days and during decay produces particles called radon daughters. These particles are solid, short-lived radioisotopes that emit alpha particles. When the radon daughters release these alpha particles into the lungs, the alpha particles penetrate cells and cause DNA damage.
Exposure To Radon
Radon is measured in Becquerel's/cubic meter (Bq/m3). Concentrations may also be reported in picocuries/liter (pCi/L) or picograms per cubic meter (pg/m3). One Bq represents the activity of a radioactive material in which one nucleus decays per second. One Bq/m3 is equal to 0.02 pCi/L and 0.0002 pg/m3.
Approximations of the dose of radiation received are reported as millirems (mrem) and "effective dose" as milliSieverts (mSv). A millirem of radiation carries the risk of a 1 in 8 million chance of dying of cancer (assuming one can extrapolate from very large to very small doses linearly). The mSv represents 100 mrem. Another measure for dose of radiation is the Working Level Month (WLM) or an average concentration of 1 Working Level (WL) for 170 hours. One WL = 8000 Bq/m3 or 200 pCi/L.
Radiation doses from radon progeny comprise more that 50% of the US population's exposure to radiation. Medical X rays provide the second highest exposure (11%). Typical indoor residential exposure is normally less than 400 Bq/m3 (generally about 100 Bq/m3) and between 10 and 20 Bq/m3 outdoors. In houses built on soils with a high uranium content, very high radon concentrations (>1000 Bq/m3) have been found.
Radon is also found in the ground, soil, rock and water. Homes that rely on well water may be exposed to some additional radon if the concentration in the well is high. However, the greatest health effect from this source is inhalation of the radon that transfers from the water to the air, and only a very small fraction of the radon in water enters the air. The EPA has recommended a standard for drinking water of 11Bq/L.
Health Effects of Radon
Lung cancer
The primary health effect of radon is lung cancer. When the radon daughters release these alpha particles into the lungs, the alpha particles penetrate cells and cause DNA damage. The damage is cumulative and can eventually cause cancer. Animal studies have shown that radon can cause cancer without the contribution of other pollutants (e.g., tobacco smoke).
The fact that radon exposure causes lung cancer was recognized first in uranium miners. One study evaluated American Indian miners who were non-smokers, and found a threefold increase in lung cancer over that experienced by non smokers who were not miners in the same community.
Smoking increases the risk of lung cancer dramatically. Early evidence for the role of smoking is the fact that before manufactured cigarettes were available, lung cancer was considered a rare disease (in spite of ongoing exposure to radon). Following the introduction of manufactured cigarettes, the incidence of lung cancers rose quickly to the point where it is now one of the most common cancers. For lifelong non-smokers, absolute risks (as opposed to excess risk due only to radon) of lung cancer (for those still alive) are 0.4%, 0.5% and 0.7% respectively at radon concentrations of 0, 100 and 400 Bq/m3. In cigarette smokers exposed to the same radon concentrations, these risks are 10%, 12% and 16% (Darby et al., 2005).
The EPA is strongly focused on the reduction of radon exposure primarily because of the enormous public health impact of its role in lung cancer in smokers. Mendez et al. (2009) analyzed smoking trends in the US and concluded that a better approach would be to concentrate on programs to reduce smoking.
Radon and Childhood Leukemia
There is some evidence that excessive radon exposure can increase the risk of acute lymphoblastic leukemia in children. One study demonstrated a 56% increase in the rate of this type of leukemia per 1000 Bq/m3-years increase in exposure (Raaschou-Nielsen et al., 2008; Harley & Robbins 2009).
Radon and Pancreatic Cancer
Radon exposure may be a significant risk factor for pancreatic cancer in African Americans, American Indians, and Asian Americans. Testing and mitigating homes for indoor radon may decrease the incidence of pancreatic cancer in these groups (Reddy & Bhutani 2009).
Radon and Other Cancers
One study of miners revealed some evidence for a relationship between other pulmonary cancers and cumulative radon exposures, but unknown factors could have influenced their results either negatively or positively (Kreuzer et al. 2008).
Protective Effect of Radon
There is some evidence that exposure to very low levels of radon may be protective, especially in smokers. Samet (2009) suggests that a non-threshold linear response is indicated by studies showing that a single alpha particle hit can permanently damage a cell. However, modeling of data from miners' studies indicate that the excess risk for lung cancer at 100 Bq/m3 is 0.l6, indicative of a protective effect. Note that risk estimates relate to 1 (no change), with estimates greater than 1 indicating increased risk and estimates less than 1 indicating decreased risk (Bogen 1998).
Standards and Guidelines
An indoor air radon concentration of 200-400 Bq/m3 has been adopted as an action or reference level by many countries. Levels less than 160 Bq/m3 indicate that no further action is necessary. The USEPA recommends remedial action if radon levels exceed 4 pCi/L (200 Bq/m3). The World Health Organization recommends a reference level of 100 Bq/m3 for radon. An acceptable radon concentration in the workplace is set at 1/3 of a WL or about 1200 Bq/m3. In September 2009, the World Health Organization released a comprehensive global initiative on radon that recommended a reference level of 100 Bq/m3 for radon and urged member countries to establish or strengthen radon measurement and mitigation programs, as well as develop building codes that require radon prevention measures in homes under construction.

Home Traffic, Dust Linked to Asthma in Kids
(HealthDay News) -- Infants exposed to outdoor traffic pollution and indoor endotoxin are at increased risk for asthma, researchers say.
Endotoxin -- a component of bacteria believed to trigger an immune response in humans -- is found in dust.
University of Cincinnati College of Medicine researchers found persistent wheezing (an early warning sign of asthma and other lung conditions) in 36 percent of 3-year-olds who were exposed to high levels of traffic pollution and indoor endotoxin as infants.
In comparison, wheezing was seen in 11 percent of children exposed to low levels of outdoor and indoor allergens as infants, and in 18 percent of children exposed to high levels of traffic pollution and low levels of indoor endotoxin. Endotoxin exposure alone appeared to have little effect on children, the study authors noted.
"There is a clear synergistic effect from co-exposure to traffic-related particles and endotoxin above and beyond what you would see with a single exposure that can be connected to persistent wheezing by age 3," study author Patrick Ryan, a research assistant professor of environmental health, said in a university news release. "These two exposure sources -- when simultaneously present at high levels -- appear to work together to negatively impact the health of young children with developing lungs."
"Traffic-related particles and endotoxin both seem to trigger an inflammatory response in the children monitored in this study. When put together, that effect is amplified to have a greater impact on the body's response," Ryan explained. "The earlier in life this type of exposure occurs, the more impact it may have long term. Lung development occurs in children up through age 18 or 20. Exposure earlier in life to both endotoxin and traffic will have a greater impact on developing lungs compared to adults whose lungs are already developed."
The findings are published in the Dec. 1 issue of the American Journal of Respiratory and Critical Care Medicine.
