ISOSTASY AND RADIOACTIVITY

Isostasy and its Meaning

The theory of isostasy supposes that, in regions which have not been disturbed recently, each vertical column of the earth's crust with a certain minimum radius and extending to a depth of about IOO km has approximately the same mass. To find the deviation from this approximation in a given region, the density must be assumed as a function of depth. Such assumptions used at present for calculat...

Isostasy, flexure, and dynamic topography

Article history: Received 12 January 2016 Received in revised form 26 May 2016 Accepted 27 May 2016 Available online 31 May 2016 A fundamental scientific question is, what controls the Earth's topography? Although the theoretical principles of isostasy, flexure, and dynamic topography arewidely discussed, the parameters needed to apply these principles are frequently not available. Isostatic fa...

Isostasy and Flexure of the Lithosphere

Radioactivity and thyroid cancer.

There is no evidence that natural radiation (cosmic radiation or from natural radioiosotopes) increases the risk for thyroid diseases. Moreover, while it has been proven that exposure to external medical radiation or to external and internal radiation by atomic bomb explosions leads to an increased risk for thyroid cancer, the medical use of radioiodine, namely diagnostic and therapeutic applic...
