resources How much Uranium is there in the Earth''s Crust

From what I know, it''s supposed that there are large amounts of Uranium in Earth''s Core, the decay of which is responsible for the core maintaining its high temperature. Mining the core is hardly imaginable, while the resources in Crust are more accessible available for mining: so how much is in the Crust, and at what levels of concentration?
