Metals like cadmium, lead, chromium, zinc, and aluminum, along with organic substances, such as phthalates, were identified in different toys by quantitative analytical techniques. Traces of thorium were detected in one of the studied samples. Although the measured radioactive dose was rather low, the presence of such a radioactive contaminant is against to the International Agency of Atomic Energy regulations. Similar toys manufactured in Brazil were analyzed and found to observe the standards defined by the National Institute of Metrology (Inmetro).833-838openAccessactinium 228bismuth 212bismuth 214calcinationgamma radiationseparation processesthermochemical processesgas chromatographylead 212mass spectraneutron activation analysisphthalatespotassium 40radium 226thallium 208thoriumtoxicityx-ray fluorescence analysisArtigo de periódico43210.1590/S0100-40422009000400002https://orcid.org/0000-0002-0606-4369https://orcid.org/0000-0002-4712-4057
