What is the curie used to measure? 0
amount of radiation equaling 3.7 1 100 disintegrations per second
amount of radiation biological material absorbs
amount of gamma radiation needed to produce a specific number of positive or negative particles
amount of radiation needed to produce 1.6 2 102positive or negative particles due to gamma rays passing through one gram of air

your answer would be “dry”

the answer is d. 74.02

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
