the unit that measures how radioactive something is by counting its tiny explosions per second.
means a unit of radioactivity equal to one million atomic disintegrations per second, named for the physicist who mapped the atom's insides.
from proposed in 1946 to honor ernest rutherford, the new zealand born physicist whose gold foil experiment revealed the atomic nucleus decades earlier; it briefly rivaled the curie before the si system standardized on the becquerel instead.

conversionone rutherford equals 10,000 becquerels
status todayofficially obsolete, replaced by the becquerel in 1975
namesake nobelrutherford won chemistry, not physics, in 1908
for instance
gold foil experiment — 1909, manchester, revealed atoms are mostly empty space
rutherford model — 1911 nuclear atom theory, replaced the plum pudding model
element rutherfordium — atomic number 104, named for him in 1997
