Radon and/or toron exhalation from samples

Rocks, soils, or other solid natural or synthetic materials in their integral form, in blocks or grinded; screens, tiles or other types of boards.

Yes. However, it is necessary to consult the LRN about the dimensions of the materials to be sent for testing.

Yes. Samples with a very small size (less than 1 L or 1 kg) may not allow reaching the detection limit of the technique or may not be representative of the material to be analyzed. The technique does not allow the analysis of samples with a volume greater than 10 L. It is recommended that samples be sent under the same conditions as they are used as the final product (eg. brick, slab, etc.).

The LRN has specific molds for carrying out the test, with dimensions of approximately 7 by 7 cm. The LRN must be consulted and the molds requested before sending the material(s) for analysis.

A sample quantity of at least 1 kg is recommended.

Yes. In the areas radon metrology and combined environmental impact analysis, among others.

LRN is qualified to execute projects with technological readiness level of 4 (technology validatation in laboratory).

Yes. Annually, the LRN participates in international proficiency cycles to determine its performance in specific tests and to monitor its quality management system. This assessment provides participating laboratories with objective means of evaluating and demonstrating the reliability of the data they are producing.
