My boyfriend gave me a gift.

Everyone was surprised by the news.

This area is seriously contaminated with radioactive isotopes.

This rock is radioactive, so care must be taken when handling it.

Radioactive elements are produced in nature and scientific experiments.

He started attending at the hospital.

Every Saturday, I do volunteer work at the local library.

His language contains many ejective sounds.

He is a very excellent tailor.

This area is off-limits due to radioactive contamination.
