US Nuclear Corp

to build first phase of advanced online radiation in-water monitors for a South Korean environmental protection agency,

Los Angeles, CA. September 10, 2015 – US Nuclear Corp. (OTCBB: UCLE) announced that it has received $118,000 in the first phase of purchase orders to build radiation in-water monitoring equipment for a South Korean environmental protection agency and research institute. “Detecting radiation in-water, real-time and continuously, is one of our specialties. This is a very exciting opportunity for us to build one of our unique systems aimed to protect the environment and population against potential radiation exposure.” commented Robert I. Goldstein, President, CEO and Chairman.

It is well known in the industry that detecting radiation in-water in a flow-through, continuous system, is a formidable and sophisticated task; there are only a few companies world-wide engaged in such production due to the complexity involved. US Nuclear Corp. specializes in this technology by offering the only commercial real-time alpha, beta (including C-14 and tritium), and gamma in-water monitors in the world. Furthermore, this equipment produces no waste stream and require no reagents to operate.

Water quality in terms of radioactivity is most often determined passively, by taking discreet samples which are then sent to a lab for analysis. However, this method can be time- consuming, inefficient, and most importantly, and it does not provide a real-time indication. Mr. Goldstein further stated, “ If an accidental spill/leak, or deliberate dumping (by terrorist act or illegal disposal) of highly concentrated radioactive material were to enter the water source, it may not be known for days, weeks, or even months later, when the sample is finally analyzed. US Nuclear Corp. realized this problem and danger associated with this and developed an automated radiation in-water monitors, designed to detect at or below DHS (Department of Homeland Security) and EPA-PAG (Environmental Protection Agency) level guidelines for drinking water quality, providing real-time data and alerts to the population.”

This order represents only the first phase of development, and additional detection sub- assemblies to be ordered and added to the system in the near future.
