Radiation in Space starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Radiation in Space.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A satellite in low Earth orbit is exposed to a radiation dose of 0.5 mSv per day. How much radiation will it accumulate in 30 days?
A solar flare increases the intensity of X-rays reaching a satellite by a factor of 10. If the normal intensity is 2 W/m2, what is the new intensity?
