Why would a doctor most likely restrict a patient's contact with other people while the patient receives internal radiation? The patient's stress and anxiety would be eliminated.
O High levels of radiation can diffuse through the patient's skin.
Social contact would increase the effect of the radiation treatment.
O Radioactive material can leave the patient's body through saliva, sweat, and urine.

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.
