Moldavites have no radioactivity. This question comes up a lot so let’s get down to it.
Moldavites are formed when sediments (clays, sands, and rocks) melt during an impact by a large meteorite. Moldavites formed from melted fragments that flew through the atmosphere. They were then scattered across the Czech Republic. These fragments became sediments because of fluvial activity. More information can be found in is moldavite from space?
The impact site for the asteroid did not contain radioactive substances like uranium. You can find the exact formula of Moldavites in , this book.
Are there any chances that the Moldavites could have been irradiated BEFORE the impact?
The radioactive material in the sediments and the impact site does not contain any. Central Europe was never subject to nuclear weapons testing. There have also not been any nuclear accidents. No radiation could therefore have been released.
Moldavite radioactivity is measured for proof
Ionizing radiation and radiation are integral parts of our lives. Invisible rays literally weave the world around them.
One sievert [Sv] can be described as a derived unit of one dose of ionizing radio radiation. We will use the equivalent dosage of Sv.s-1 to determine the duration of radiation.
Similar dosages for humans are shown in the following examples
X-ray 1 uSv of arm
X-ray chest 20 uSv
Airplane flight (4000 km) 40 uSv
Engineer in a nuclear plant 0,4 MSV/year
People living in the Dukovany area receive 0,005 MSV/year
Digestion of a banana 0,1 MSV
It is thought that the lowest yearly dose will increase the risk of getting cancer 100 Sv
