Why did ‘Nick Fury’ get sick in Secret Invasion?

‘Fury’ got sick when he visited Gravik in New Skrullos because the Rebel Skrulls built their base at an abandoned nuclear power plant.

What were the pills Fury was taking in Secret Invasion?

‘Fury’ was presumably taking iodine pills (or a super S.H.I.E.L.D. equivalent) because they help the body cope with the symptoms of radiation poisoning. Basically, iodine pills (or potassium iodine, at least) can help delay radioactive material from being absorbed by the thyroid preventing the person from developing thyroid cancer.
