Asset Retirement Obligation Disclosure [Abstract]

NOTE G - ASSET RETIREMENT OBLIGATIONS

We provide for retirement obligations relating to future decommissioning costs associated with certain of our equipment and buildings in our brachytherapy segment. The liability is recorded at present value by discounting our estimated future cash flows associated with future decommissioning activities using our estimated credit-adjusted borrowing rate. The asset retirement obligation has been recorded in the accompanying consolidated balance sheets and will be adjusted to fair value over the estimated useful lives of the assets as an accretion expense. Changes in estimated future cash flows are adjusted in the period of change.

The following summarizes activity in our asset retirement obligation liability (in thousands):

	Year ended
	2012		2011
Asset retirement obligation at beginning of period	$	807	$	749
Accretion expense		64		58
Asset retirement obligation at end of period	$	871	$	807
