The personal strain about radioactive workers had some main influential factors of, such as physical environment, age, role boundary, radioactiveage, responsibility, collaboration and role overload.
Planetary scientists can determine a rock's age by calculating how many radioactive "parent" isotopes of a particular element have decayed into "daughter" isotopes.
The downsides were also great. Marie's work with radioactive elements inflicted serious burns to her arms and hands - and perhaps triggered the leukemia that killed her at age 58.
