US Nuclear Corp. was upgraded to the OTC-QB market from the OTC Pink Marketplace this week, a move that helps the company engage new investors.

The Canoga Park manufacturer of radiation detection devices also benefits from the upgrade with increased visibility and building shareholder value.

Chief Executive Robert Goldstein said the upgrade is one more step for the company as it grows and evolves.

“We are looking forward to increasing our company’s reputation and visibility on the market,” Goldstein said in a statement.

The OTC-QB, also known as the “venture market” was created in 2010 and is the middle tier of the three markets making up the OTC. It is made up of early-stage and developing companies.

The company announced the exchange shift Wednesday. Shares in US Nuclear (UCLE) closed Thursday unchanged at 97 cents on the over-the-counter market.
