2. Test results
2.1 Radioactivity
Natural radiation exposure is composed of cosmic and terrestrial radiation. Humans are mainly
subject to internal exposure due to radon gas. In addition to radon in ground air due to geologi-
cal conditions, an increased concentration of radon may be found in living spaces because of
certain building materials. Breathing in the gas over a long period of time may expose the lungs
to radioactive radiation. While most radon particles are exhaled again, its radioactive decay
products can be deposited in the lungs. In 1999, the Radiation Protection 112 document issued
by the European Commission proposed an Activity Concentration Index (ACI) for building mate-
rials. The limit is ACI  1.00 while the Institut für Baubiologie Rosenheim sets the ACI limit at  0.75.
Gamma-spectrometry is used to determine the natural radioactivity.
Evaluation:
The tested boards with a value of 0.06 are below the allowable limits and are therefore safe in
regards to radiation exposure.
2.2 Biocides, OHCs, phthalates
Biocides, pyrethroids, organic halogenated compounds (OHCs) or phthalates are added to dif-
ferent building materials to produce various properties such as pest resistance and durability, or
also for technical processing reasons. Organic halogenated compounds are further differentiat-
ed into AOX (adsorbable organic halogens), POX (purgeable organic halogens) and EOX (ex-
tractable organic halogens) according to DIN 1485. In order to prevent the impairment of health
due to the classes of compounds named above, limit values have been established for safe use
of the building materials in living spaces and these should not be exceeded.
Test method: The tests are carried out by means of extraction based on DFG-S19 and coulome-
try accoriding to DIN 38414-S17/18.
