The Antarctic ozone hole (which is larger than its Arctic cousin) is usually healed before UV-B from the Sun arrives. However, a large ozone hole will place the southern parts of Chile and Argentina at risk first, then New Zealand, Australia, and South Africa at risk (in succeeding orders)
The Arctic (northern) ozone hole is naturally smaller than the Antarctic (southern) ozone hole, and they occur about 6 months apart in time.... when it is winter at that pole.
Answer:
No country has a depletion issue overhead under normal conditions. The two thinning areas occur ONLY over the poles during their winter months. Australia has seen a portion of their country fall under the thinning area some winters, but that is a rare occurrence. No thinning has occurred over areas that maintain the sun year round.
The process that allows for the ozone layer to thin is a lack of sunlight. No science group blames man or CFC's for the issue itself, in fact the largest known thinning area occurred in 1858 before CFC's were used.
What some groups claim (and there is evidence to support this), that CFC's contribute to this issue.
It is not so much a country . . . but the ozone layer is thinnest above the north pole and above the south pole. This is the way it has been for millions of years, I suspect.
Since the largest Ozone hole is above Antarctica, it reaches the maximum amount of UV radiations.
The ozone layer is thinnest over Antarctica, which is a continent, but not a country.
Countries where it is thin are Australia, New Zealand, Chile and Argentina.
The ozone layer is very thin.
The thin layer of gas is popularly known as ozone layer. It is due to the properties of ozone, that UV is absorbed.
The ozone layer!
The ozone layer this during winters. It is due to the increase in depletion at low temperature.
ozone is not considered as a layer because it is very thin. Troposphere is considered a layer.

The stratosphere contains the ozone. IT is present as ozone layer.
Thin layer of compound ozone is ozone layer. It protects from harmful UV rays.

CFC's are the reason. They react with ozone to deplete it and makes the layer thin.
Ozone hole is the term. It is the thinning of ozone layer.
The ozone layer gets thin by man made destructive products. Various ODS are responsible for that.
There is a thin layer of ozone that covers entire surface. It is called ozone layer and protect us too.
The ozone layer is very thin.
Ozone layer is thin over Australia. It is due to its location near poles.
Ozone layer is the layer. It contains ozone molecules.
Health Hazards result from a thin ozone layer. There are skin cancer, eye cataract etc.
