radon in shower water

As private wells tap ground water, dissolved radon escapes from the water and gets into household air in the course of dishwashing, showering, and other water-using activities. I can’t tell you how many customers we speak with in the period of a month who tell us this same exact story. Radon enters household air supplies primarily as a result of gas being released from the soil directly under a home. Then, some well meaning but partially misinformed advise arrives from a friend. When you turn on your shower or any faucet, it releases the radon into the air. Purchase a radon in water … Up until only the last 5-10 years most of the media discussions and concerns regarding Radon health issues was centered primarily on how much Radon gas a person breathed in through their home’s overall interior air supply. Even if radon is dissolved in the water, most of it is inhaled, rather than absorbed through the skin. If you have your water tested and it indicates high radon levels, there are treatments that will remove radon from … If you read our previous article The Difference between Water Radon and Air Radon, you already know that Radon gas is always looking for a way to escape; both from the earth underneath your home as well as from the water that comes in from your well. Radon in water can be released whenever you wash clothes, dishes, shower, or any other activity that uses water. shower (high transfer) vs. running water in a sink (low transfer); and The water and air temperatures (as the temperature of the water increases, radon transfer increases). Open surface water simply allows the radon to be released harmlessly into the atmosphere. Radon in warm shower water ranged from 24 to 390 Bq L −1, with a median of 124 Bq L −1. Radon may be present in both soil and water. The lifetime inhalation risk from 10,000 pCi/L in water (or one pCi/L in air) is about two in a thousand for never-smokers and about nine in a … Due to the increasing ratio of Rn decay products to Rn, alpha energy exposure is greatest several minutes after the shower is turned off. HOW CAN RADON LEVELS BE REDUCED? Radon was determined in well water, bathtub tap water, aerated shower water, and indoor air using multi-day tests and /in situ/ counting of bathroom air before, during, and after experimental showers. When you take a shower or use the washer or dishwasher radon in the water is released into the air and the levels will rise. Radon in warm shower water ranged from 24 to 390 Bq L −1, with a median of 124 Bq L −1. When you shower and bathe, be sure to run the bathroom ventilation fan to keep your radon exposure as low as possible. Prior to this period, most home inspectors would advise their customers to do a standard air Radon test kit to measure the Radon levels in their soon to be home. These kits are left inside a home for 2-4 days, usually in a basement or first floor living space. As indicated above, the radon that off-gasses to the air and is subsequently inhaled is the real concern. The kits are collected after the “set” period, then tested to determine the average, overall indoor air Radon count …in other words, they tell you the average amount of Radon a home has at any given point in the home’s living space. It is common in the earth's crust. Radon dissolved in water enters your home in greatest quantities when showering, dish washing, and when doing laundry. Radon is a tasteless, odorless gas produced through the natural breakdown of Uranium in the earth’s bedrock. Exposure can take place when taking a shower, doing laundry, or washing dishes. I do sell radon aeration systems for well water. Radon in cold and hot water from the bath/shower room shower head averaged 60±1 and 38±2 Bq l −1, respectively, whereas hot water collected in the shower at the tub base averaged 5±1 Bq l −1 or a 92 % radon loss to air. The same radon can be aerated by being run through laundry machines, shower heads and faucets, poisoning the air as well as the water. The majority (90%) of the risk from radon in water is from inhaling the radon released from the water in household uses such as laundering and showering as illustrated on the graph to the right, where: s - indicates the time of a shower, l - laundry, b - bath, d - dishwasher, o - open window, and; c … While the highest risk for radon gas poisoning is via a foundation crack, every year about 30 in 1,800 deaths per year is thought to be caused by radon in a water supply. How? In order to examine one such incremental increase in exposure, variations in Rn in water and indoor air in 18 houses with private wells in western North Carolina (USA) were investigated. After 20-min showers in bathrooms with closed doors, peak Rn in air increases (above background) ranged from 71 to 4420 Bq m−3 (median 1170 Bq m−3).
