0 a unit, used especially in the past, for measuring radioactivity
Its alpha activity was about 10,500 curies and the beta/gamma activity about 560,000 curies.
The radioactivity of wastes held prior to treatment and disposal amounts to some 550 mega curies.
Five curies out of the 26 were contained in a single delivery of tritiated water.
It is believed to hold a radioactive iridium-192 source, of activity 8 curies in 1980.
Alpha emitters will drop from 5,000 curies a year in 1973 to 20 a year by 1991.
The total alpha radioactivity in the waste at the time of dumping was 8,279 curies and the beta-gamma radioactivity 578,845 curies.
Three curies, consisting of 220 consignments (138 to hospitals), had a half-life of less than a fortnight.
What is the radioactive source, and what is its strength in curies?
