Asset Retirement Obligation [Abstract]

9. Asset Retirement Obligation

In September 2007, an asset retirement obligation of $473,096 was established representing the discounted cost of the Company's estimate of the obligations to remove any residual radioactive materials and all leasehold improvements at the end of the lease term at its new production facility. The estimate was developed by qualified production personnel and the general contractor of the facility using Level 3 fair value inputs.

During the years ended June 30, 2014 and 2013, the asset retirement obligations changed as follows:

	2014		2013
Beginning balance	$	792,242	$	724,298
Accretion of discount		74,318		67,944
Ending balance	$	866,560	$	792,242

Because the Company does not expect to incur any expenses related to its asset retirement obligations in fiscal year 2015, the entire balance as of June 30, 2014 is classified as a noncurrent liability.
