The Myth of Moldavites Radioactivity

Moldavites do not have radioactive properties. Nevertheless, this question does come up quite often so let’s dive into the myth of Moldavites radioactivity.

Moldavites resulted from the melting sediments (clays, sands & rocks) following the impact of an asteroid. Moldavites, which were created from melting fragments of rocks and clay, were distributed throughout the Czech Republic. These fragments, which were formed by fluvial activity, were washed downstream, where they settled as the sediments we now find. To learn more, please visit the how Moldavites are formed page.

The impact area of the asteroid had no radioactive materials, including uranium. This book contains the exact chemical formula for Moldavites.

Is it possible for Moldavites to have been irradiated even after the impact?

Radioactive material is not found in the impact sites or the sediments. Central Europe has never seen any nuclear weapons testing or had any nuclear accidents. Thus, there was no radiation that could have been produced.

Moldavite radioactivity can be measured and proved

Theoretical intro

Radiation is an integral part our daily lives. The invisible radiations of radiation are interwoven throughout the environment.

One sievert [Sv] represents one unit of one ionizing dose. We will use the equivalent dose of Sv.s-1 which refers to the radiation duration.

Consider these examples of equivalent dosages to humans

Xray of arm 1 (uSv)

X-rays of chest 20uSv

Airplane flight (4000 km) 40 uSv

Engineer at a nuclear powerplant 0,4 mSv/year

Population in the Dukovany nuclear area receives 0,005mSv/year

Digestion of banana 0,1 mSv

This is believed to increase the risk of cancer 100 Sv.
