Roentgen:
A unit of radiation exposure equal to the quantity of ionizing radiation that will produce one electrostatic unit of electricity in one cubic centimeter of dry air at 0°C and standard atmospheric pressure.
[After Wilhelm Konrad Roentgen.]
Natural radioactivity can cause spontaneous mutations in an organism's DNA. These mutations are often referred to as spontaneous mutations or radiation-induced mutations.

The radioactivity of uranium was discovered in 1896 by the French physicist Henri Becquerel.
Recorded observations and measurements from an experiment are referred to as data. The data can either be quantitative or qualitative.
James Alfred Sorensen has written: 'Methods for quantitating radioactivity in vivo, by external counting measurements'
The closeness of measurements to each other is referred to as precision. In other words, precision indicates the degree of consistency between individual measurements.
In metric measurements, the .45 ACP is referred to as 11.43x23mm.

Radioactivity affect the water molecules. Radioactivity makes it harmful
What other sort of radioactivity is there?
Radioactivity can be induced in ordinary matter by artificial transmutation.
no but she built the knowleage of radioactivity.
