The full impact of radiation exposure was hidden for many years by Soviet authorities.

The general consensus of health studies conducted at the site since it was closed is that radioactive fallout from nuclear testing had a direct impact on the health of about 200, 000 local residents.

Specifically, scientists have linked higher rates of different types of cancer to post-irradiation effects.

Likewise, several studies have explored the correlation between radiation exposure and thyroid abnormalities.
