5 PHASE 2 RADON SURVEY, PEI 1.0 INTRODUCTION ALL-TECH Environmental Services Limited was contracted by Prince Edward Island s Department of Health to conduct additional radon testing at selected sites across Prince Edward Island. The purpose of the survey was to provide statistically relevant province -wide data for radon concentrations and geographical regions within the province of Prince Edward Island as well as provide re-testing of previous elevated sample locations identified in June 2008 Radon Survey final report prepared by ALL-TECH Environmental Services Limited. The monitoring period commenced on December 8, 2008 and was completed on January 9, 2009 at predetermined sites across Prince Edward Island. 1.1 Background / Objectives Radon is a radioactive colorless, odorless gas produced by the natural breakdown of uranium in the soil. Radon will seep into structures through cracks in foundation walls or floors. Radon is heavier than air and therefore tends to accumulate in the lower areas of buildings such as basements and crawl spaces. The gas will dissipate in upper building levels so the survey will concentrate on the lowest occupied levels of all test locations. Radon gas is of public health concern as it may be responsible for up to 10% of all lung cancers. The gas decays into radioactive products when inhaled and becomes trapped in the lungs. An individual s risk of getting cancer will depend on radon concentrations and the length of exposure. Health Canada has recently lowered the indoor air quality radon guideline from 800 Becquerels per cubic metre (Bq/m 3 ) of air to 200 Bq/m 3. Prince Edward Island is not known to have large concentrations of uranium in the soil. However uranium does exist in all soil and is not uniformly distributed. Therefore, this study shall be used to provide statistically relevant province -wide data for radon concentrations and geographical regions within the province of Prince Edward Island. 1

6 PHASE 2 RADON SURVEY, PEI 2.0 METHODOLOGY Survey methodology included deploying and collecting 410 long term samples (3 months) in one hundred and six (106) provincially owned properties across Prince Edward Island including schools, seniors housing, correctional centres and others (see Table 1 summary below). In addition, 41 long term samples (3 months) were re-tested within 20 provincially owned properties from the previous years sampling event (see Table 2 summary below). Properties and number of samples per building were predetermined by Prince Edward Island s Department of Health. Table 1 Schools (Eastern) Summary of Buildings Schools Schools (Western) (French) Seniors Housing Correctional Centres & Others Total Table 2 Summary of Retest Locations from Phase 1 Monitoring Schools Hospitals / Manors Seniors Housing Total For the purposes of Quality Assurance / Quality Control (QA/QC) for the survey and retest areas, a total of thirty-seven (37) field duplicates and eighteen (18) field blanks were included. This represents approximately 10% and 5% respectively for the samples collected. Sample deployment commenced on January 18, 2008 and was completed on January 25, The collection of the samples was from April 21 to April 29, For each site location, summary reports have been developed describing the building ID, address, sample bar code number, deployment date, retrieval date, room, floor and site sample photo. Summary reports have been divided into separate tabs under the following headings and are found in Appendix A: 2

7 PHASE 2 RADON SURVEY, PEI Schools (Eastern) Schools (Western) Schools (French) Seniors Housing Correctional Centres and Others Re-test locations Buildings are listed in alphabetical order within their respective sections. 2.1 Type of Detectors The survey and re-test locations included 451Alpha Track detectors which were deployed by the consultant at predetermined locations and sent to Lex Scientific in Guelph, Ontario for analysis (see Table 2 summary below). The Alpha Track method uses a small cellulose-nitrate film attached to the side of a small plastic sample cup. The film is not affected by light or any other form of electromagnetic radiation. The film is only sensitive to alpha particles emitted by daughter products of uranium (mainly radon). The processing of the detectors entails the etching of the nitro-cellulose film. This etching process highlights the damage tracks caused by the alpha particles when they impinge on the nitro-cellulose film. Table 3 Summary of Samples Deployed Survey Totals Re-test totals Samples Duplicates 34 3 Blanks 17 1 Totals *Note: 21 samples were not found at the time of collection. Therefore, four hundred and thirty (430) of the four hundred and fifty-one (451) samples forwarded to laboratory for analysis. 3

8 2.2 Measurement Locations PHASE 2 RADON SURVEY, PEI The alpha track detectors come sealed in foil pouches and become active once the pouch is opened. Once at each test location, these devices were opened and the following information recorded: The monitors unique bar code If the sample was a field duplicate or field blank Start date & time Sample Location Floor Level Sample Location Photo Upon collection of the devices, the devices were sealed in zip-locked bags and the sample time and date were recorded and sent to Lex Scientific for analysis. Upon collection of the devices, 21 of the 451 monitors were missing and not reported at the time of collection. ALL-TECH used the sampling approaches established by Health Canada from Guide for Radon Measurements in Public Buildings* (*Schools, Hospitals, Care Facilities, Detention Centers) as amended November 13, 2007 and best judgement based on experience. Measurement locations were primarily based on lowest occupied room sites where practical. To provide a defensible radon concentration estimate, measurements were taken in the lowest-level occupied rooms of the building. Special attention was made to avoid measurements in bathrooms, closets, cupboards, sumps, crawl space, or nooks within any foundation. In addition, the presence of air currents caused by heating, ventilating and air conditioning vents, doors, fans, and windows were avoided where practical. 3.0 SURVEY FINDINGS The survey included predetermined test locations as selected by the provincial Department of Health. In total, three hundred and fifty nine (359) sample locations as well as 34 duplicates and 17 field blanks were deployed and collected to determine radon concentrations in one hundred and six (106) provincially owned buildings across 4

9 PHASE 2 RADON SURVEY, PEI Prince Edward Island. Samples which exceeded Health Canada guidelines ranged from Bq/m 3. In addition, thirty seven (37) samples as well as 3 duplicates and 1 field blank were deployed in twenty (20) predetermined re-test locations from the previous years sampling event. Samples which exceeded Health Canada guidelines ranged from Bq/m 3. Table 4 illustrates a summary of the number of buildings affected. Table 4 Summary of Results Number of Number of Buildings tested Buildings re-tested for study from previous year Study Number Buildings identified exceeding Health Canada Guidelines Re-test location Buildings identified exceeding Health Canada Guidelines CONCLUSIONS AND RECOMMENDATIONS Health Canada has established a Timeframe to Remediate based on radon measurements exceeding the guideline of 200 Bq/m 3. Table 5 Health Canada Timeframe to Remediate Radon Concentration Recommended remedial action time Greater than 600 Bq/m 3 In less than 1 year Between 200 Bq/m 3 and 600 Bq/m 3 In less than 2 years Less than 200 Bq/m 3 No action required Mitigation decisions should always be based upon 2 tests. Based on the survey results, the following remedial action listed in Table 6 is recommended for buildings identified with radon levels above Health Canada guidelines: 5

Inconsistent with additional samples from the same building as well as Quality Control. Radon Reduction Techniques There are several methods to lower radon levels in dwellings. Some techniques prevent radon from entering your home while others reduce radon levels after it has entered. Soil suction prevents radon from entering the dwelling by drawing the radon from below the structure and venting it through a pipe, or pipes, to the air above the dwelling where it is quickly diluted. Any information available about the construction of the dwelling could assist a contractor in choosing the best system. 6

11 PHASE 2 RADON SURVEY, PEI Other Types of Radon Reduction Methods Other radon reduction techniques that can be used in any type of dwelling include: sealing, house/room pressurization, heat recovery ventilation, and natural ventilation. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction. Sealing the cracks limits the flow of radon into your home thereby making other radon reduction techniques more effective and cost-efficient. It also reduces the loss of conditioned air. Building/room pressurization uses a fan to blow air into the basement or a living area from either upstairs or outdoors. It attempts to create enough pressure at the lowest level indoors (in a basement for example) to prevent radon from entering into the building. The effectiveness of this technique is limited by construction, climate and occupant lifestyle. In order to maintain enough pressure to keep radon out, the doors and windows at the lowest level must not be left opened, except for normal entry and exit. This approach generally results in more outdoor air being introduced into the home, which can cause moisture intrusion and energy penalties. Consequently, this technique should only be considered after the other, more-common techniques have not sufficiently reduced radon. A heat recovery ventilator (HRV), also called an air-to-air heat exchanger, can be installed to increase ventilation which will help reduce the radon levels in dwellings. An HRV will increase ventilation by introducing outdoor air while using the heated or cooled air being exhausted to warm or cool the incoming air. HRVs can be designed to ventilate all or part of a dwelling, although they are more effective in reducing radon levels when used to ventilate only the basement. If properly balanced and maintained, they ensure a constant degree of ventilation throughout the year. HRVs also can improve air quality in houses that have other indoor pollutants. There could be significant increase in the heating and cooling costs with an HRV, but not as great as ventilation without heat recovery. Some natural ventilation occurs in all dwellings. By opening windows, doors, and vents on the lower floors you increase the ventilation. This increase in ventilation mixes outdoor air with the indoor air containing radon, and can result in reduced radon levels. However, once windows, doors and vents are closed, radon concentrations most often return to previous values within about 12 hours. Natural ventilation in any type of dwelling should normally be regarded as only a temporary radon reduction approach 7

12 PHASE 2 RADON SURVEY, PEI because of the following disadvantages: loss of conditioned air and related discomfort, greatly increased costs of conditioning additional outside air, and security concerns. Once any of these reduction techniques have been applied, follow up testing should be carried out to verify the effectiveness. 5.0 LIMITATIONS The findings contained in this report are based upon conditions as they were observed at the time of the survey.
