Why is phosphorescence forbidden?
Phosphorescence is a relatively long-lived light emission from a material The phosphorescence lifetime is significantly longer than the fluorescence lifetime of the material The electronic transitions that result in phosphorescence emission are sometimes called ‘forbidden’ transitions
Who is the inventor of radioactivity?
Henri Becquerel
Why is it called radioactive?
What causes radioactivity? As its name implies, radioactivity is the act of emitting radiation spontaneously This is done by an atomic nucleus that, for some reason, is unstable; it “wants” to give up some energy in order to shift to a more stable configuration
Why does radioactivity kill?
Radiation damages your stomach and intestines, blood vessels, and bone marrow, which makes blood cells Damage to bone marrow lowers the number of disease-fighting white blood cells in your body As a result, most people who die from radiation sickness are killed by infections or internal bleedin
Why is Marie Curie radioactive?
Curie died on July 4, 1934, of aplastic anemia, believed to be caused by prolonged exposure to radiation She was known to carry test tubes of radium around in the pocket of her lab coat Her many years working with radioactive materials took a toll on her health
How much radiation is safe for human?
The maximum permissible exposure for a person under 18 working with radiation is one-tenth the adult limit or not to exceed 500 millirems per year above the 300+ millirems of natural sources, plus medical radiatio

Did Marie Curie died from radiation?
Answer: Marie Curie died on, in Savoy, France She died of aplastic anaemia, a blood disease that often results from exposure to large amounts of radiatio
How much radiation is a Curie?
1 curie = sup>10 radioactive decays per second [exactly] In the International System of Units (SI) the curie has been replaced by the becquerel (Bq), where 1 becquerel = 1 radioactive decay per second = sup>-11 Ci The magnitude of radiation exposures is specified in terms of the radiation dose

How much is a Curie?
As such, 1 Ci is equal to 37 billion (37 x 1010) disintegrations per second, so 1 Ci also equals 37 billion (37 x 1010) Bequerels (Bq) A curie is also a quantity of any radionuclide that decays at a rate of 37 billion disintegrations per second (1 gram of radium, for example)
