The uncertainty for attempting to extrapolate the yearly radon concentration from a five to seven day sample is huge: about +/- 90% (at the 90% confidence level) 17. For this reason, a single CC reading (or indeed several) cannot be used to estimate the annual radon exposure in a house.
The Defeasance Clause. As part of a mortgage agreement, the defeasance clause provides the buyer the right to secure the title, or deed, for the property once the debt is paid in full. Prior to that time, the financial institution backing the loan has all rights to the title as it functions as collateral for the associated debt.
If the mortgagor failed to pay the debt, even by only one day, the mortgagee's title became an estate in fee simple absolute, which gave the mortgagee absolute ownership of the property. A defeasance clause embodies these common-law principles that govern this type of mortgage agreement. Defeasance clauses are not found in mortgages based upon the lien theory, observed in most states. The mortgage creates a lien for the mortgagee on the mortgaged property, which gives the mortgagee the right to its possession only after the mortgage has been foreclosed.
