abstract: The data cover the results from pre- and post-mitigation radon tests conducted in New Jersey during calendar year 2009. The statute and regulations at N.J.S.A. 26:2D-73 and N.J.A.C. 7:28-27 et seq., respectively, require the confidentiality of the address at which radon testing is conducted. Therefore, the individual addresses cannot be submitted in this data set and the data for an individual address will be displayed as city, municipality, county and zip code. All pre- and post-mitigation tests were conducted by either New Jersey certified measurement technicians or specialists or by homeowners. Tests were conducted using radon measurement devices provided by New Jersey certified radon measurement businesses. All tests are reported using strict, standardized reporting requirements that include the full address (street, city, incorporated municipality, state, zip code), device model number, sample reference number or serial number, location of the test (floor), whether closed house conditions were maintained, building type (residential, non-residential, school, child care, child care center in a public school), structure type (basement, crawlspace, slab on grade), test type (standard, duplicate, blank), whether the test is conducted during a real estate transaction, whether it is a post-mitigation test, the individual that deployed and retrieved the test, and the date and time the test was started and stopped. Data are submitted electronically and are electronically transferred to the Oracle database. The data are checked for completeness and specific errors before transfer to the database. The address is checked by the database to ensure that the incorporated municipality matches the correct county and if it does not, the address is checked and fixed before it is transferred to the database and, if it cannot be fixed, the data for that test is not transferred.
purpose: The New Jersey regulations at N.J.A.C. 7:28-27 et seq. require that all radon test results be reported monthly to the New Jersey Department of Environmental Protection. The New Jersey certified radon measurement businesses that conduct the testing are required to report all tests in a specified format so that the data can be transferred to the Oracle database. These data are used to determine the number of tests that are conducted at the municipality, county and state levels. The testing rates may be used to target specific outreach to municipalities or areas of New Jersey. Radon testing is voluntary in New Jersey, so outreach is an important tool to encourage people to test their homes. In addition, the data are used to generate the New Jersey Radon Potential Map, which shows the percentage of homes in New Jersey that have radon concentrations greater than or equal to 4 pCi/L. If less than 5% of the homes have radon concentrations greater than or equal to 4 pCi/L, the municipality is designated as Tier 3 (low radon potential), if 5-24% of the homes have radon concentrations greater than or equal to 4 pCi/L, the municipality is designated as Tier 2 (moderate radon potential), and if 25% or more of the homes have radon concentrations greater than or equal to 4 pCi/L, the municipality is designated as Tier 1 (high radon potential). This map is used by the New Jersey Department of Community Affairs to require, through the New Jersey building code, that all homes built in Tier 1 municipalities are built with radon resistant construction features (including a layer of gravel, vapor barrier, and PVC pipe that extends from the floor of the foundation, up through the roof).

data_completeness: The data extract is based upon radon test results submitted on a monthly basis by New Jersey certified radon measurement businesses during calendar year 2009. By New Jersey regulation, N.J.A.C. 7:28-27 et seq. (Certification of Radon Testers and Mitigators), certified radon measurement businesses are required to submit to the Radon Section "by the first day of each month the results of all radon and radon progeny measurements performed during the second previous month. For example, the results from May testing are to be submitted July 1." Data submissions are required to be submitted by email as a tab-delimited ASCII file. The data file is then appended to an Oracle-based import table that verifies that the data fields are in the correct format and that the number of characters in each data field is not exceeded. At this point the imported data undergo a data validation check, which verifies the following information: A. The county and incorporated municipality where the test was deployed is checked with a data table that contains different variations of how the municipality name is entered (for example, Ewing, Ewing Twp or Ewing Twp.) and the standard name that gets entered into the database (in this case Ewing Township). B. Building type – Makes sure that either R – Residential, N – Non-residential, D – Daycare facility, S – School or P – Daycare facility in a school is entered. C. Structure type – Makes sure that either B – Basement, C – Crawlspace, S – Slab-on-Grade, O – Other or U – Unknown are entered. D. If the building type is either a school or a daycare facility in a school, the program verifies that both the school code and room ID fields are populated. E. If the school code field is populated the program checks that the building type field indicates either a school or a daycare facility in a school. F. If a test was conducted in either a school or a daycare facility in a school, the program verifies that the Owner, School Name field is populated. G. A test reference number is entered for measurement data H. A street is entered I. The city field is populated but that name is not verified J. If the municipality, county and part of the street are entered, the program checks if a similar address was already entered (to avoid having the same address entered more than once). K. The zip code field is populated L. The floor tested field is populated M. The analytical lab that analyzed the alpha track, charcoal canister or liquid scintillation test device is checked to make sure it is valid N. The test condition field is populated O. Indicates that test was or was not real estate-related P. The test start and stop fields are populated with a valid date Q. The test start and stop times are populated with a valid time (except for alpha track and long-term electret devices) R. The sampler deployed and sampler retrieved fields are populated with a valid number S. The media tested was A for air or the media mitigated was either A or W (for water). T. For portable devices (CRM’s, CWLM’s, ES, EL’s and RPISU’s devices) the manufacturer, model number and serial number fields are populated. U. That the QA field that records if the test is either an S - standard, D - duplicate or B - blank test is populated and that the code entered is valid. V. If the radon reading, radon progeny reading or margin of error fields contains a non-numeric symbols that entry is flagged. W. If the room field contains kitchen, bathroom or laundry room the program flags that test so that the Radon Section can determine if the location was valid considering the conditions under which the test was conducted Once this data validation is completed the records from the import table are merged into the address and the radon test result tables. The radon test results are being sent from a modified New Jersey EN Browser data flow developed specifically for uploading data to the CDC. This data flow does not send exact address locations (only the county municipality name, locality names and zip codes are sent). If that city is invalid that test result would not be displayed in the data flow.
