Question 1

What is the difference between Sievert and Gray?

Accepted Answer

Gray (Gy) measures absorbed radiation dose, while Sievert (Sv) measures biological effect. 1 Gy of X-rays = 1 Sv, but other radiation types differ.

Question 2

How do I convert between radiation units?

Accepted Answer

Enter your value and select the source unit. The converter handles Sievert, Gray, rem, rad, and activity units like Becquerel and Curie.

Question 3

What radiation levels are considered safe?

Accepted Answer

Background radiation is about 2-3 mSv/year. Occupational limits are typically 20 mSv/year. This converter helps understand radiation measurements.

Question 4

What is the difference between activity and dose?

Accepted Answer

Activity (Becquerel/Curie) measures radioactive decay rate, while dose (Gray/Sievert) measures energy absorbed. They are related but distinct measurements.
