Radioactive iodine (radiolodine) is given to patients with some forms of thyroid cancer in order to destroy the cancer cells. 1311 has a half-life of 8 days. Women who have been treated with 1311 are
advised to not become pregnant for 180 days (approximately 6 months) to avoid the radioactive
contamination of a developing fetus.
If a woman has been given a dose of 10 mci (millicurie, a measurement of radiation), how much 1311
will still be in her system when she can safely become pregnant?
3.125% of the original isotope
22.5 x 10-6 mci
1.7 x 10-6 mci
There will be no iodine-131 left in her system after 180 days.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

=more the cloud cover, the lesser the

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
