South Korean experts say they have not detected any radioactive isotopes from North Korea's nuclear test, hampering efforts to assess the device.
It would also not itself become radioactive by absorbing neutrons.
As 50% of inactive atoms would have spread throughout the whole mountain as a result of 50% remaining rule applied, it would turn up that it would be easily to locate a small portion of rock from the mountain that would not respond to radioactive decay.
People who lived locally but were not exposed to the radioactive sands had significantly fewer mutations.
This is because the waste consists of barrels of sludge containing compounds such as nitrides, oxides and water that are not, themselves, radioactive.
Fusion produces no greenhouse gases, and, unlike nuclear fission, it does not produce long-lived radioactive waste.

But dating things as old as this, which is done by studying the products of radioactive decay, is not a precise science.
ECONOMIST: Some new ideas about why life on Earth has periodic crises
You may also consider the factual history of the apartment building in Japan that was mistakenly constructed with some highly radioactive material, the inclusion of the radioactive construction material was not discovered until many years later, the residents were studied extensively for evidence of increased cancer.
We're not sure if these alien rocks are radioactive, but if Kryptonite did come in art form, it'd probably resemble something like what we see below.

They did not understand what had happened immediately because the radioactive gas had no odour or colour.
For example, the new EPA guide refers to International Atomic Energy Agency guidelines that suggest intervention is not necessary until drinking water is contaminated with radioactive iodine 131 at a concentration of 81, 000 picocuries per liter.

The main reactor building will not be pulled down until about 2100 when the radioactive levels in the building become safe.
The annual report has revealed that DSRL was awaiting the outcome of an investigation into why not all procedures were followed in the movement of radioactive material.
One doctor confided that he and his colleagues were not completely sure of the content of the toxic waste, and advised concerned patients not to drink milk in case the waste was radioactive.
The campaign group said it commissioned independent consultants to review the methods used to assess the environmental impacts of radioactive emissions, and found they would not be sufficient or wide-ranging enough to discover the effects on the marine environment.
What does that mean? 30 miles out, it would not be dangerous to come into contact with water with low radioactive iodine concentrations.
That also means they cannot damage the walls of the apparatus, since they do not fly through them, and makes the whole operation less radioactive, and thus safer.
An airplane crash does not have the possibility of the continued risk of killing people by radioactive contamination or genetic mutation decades or even permanently into the future.
In the past few weeks, Cosgrove and others have come to find out that radioactive tritium leaked from a pipeline leading off the plant grounds not just once in 2000, as the community had initially been told, but at least three other times as well, dating back to 1996.
