Description

Radioactive microparticle interactive measurement system and method {RADIOACTIVE MICROPARTICLE INTERACTIVE MEASUREMENT SYSTEM AND METHOD}

The present invention relates to a radioactive fine particle interactive measurement system and method, and relates to a technology capable of simultaneously measuring radiation and fine dust.

Nuclear power plants pay attention to the health management of workers from harmful environments by using a measuring device for each purpose of radiation or fine dust generated in a dismantling workshop or harmful environment.

When a worker working in a hazardous environment is exposed to radiation or fine dust for a long time, it has adverse effects on the human body, and in severe cases, it corresponds to a harmful factor leading to death. Such radiation and fine dust may accumulate inside the human body as it flows into the human body during work, even if a pleasant state is maintained through thorough management.

It is difficult to accurately measure radiation and fine dust accumulated inside the human body of workers, and it is difficult to provide feedback through immediate hazard diagnosis by identifying the degree of harm through regular health management.

In general, radiation and fine dust must be measured using measuring devices required for each environment in dismantling workshops with high concentrations of radiation and fine dust and daily life with low concentrations, but user convenience and economic feasibility are reduced in installing and maintaining each equipment. However, there is a problem in that the function of analyzing the user's health condition through the data measured by each measuring device is not provided.

Therefore, in order to solve this problem, it is necessary to develop a technology capable of conveniently managing the health of workers working in harmful environments through a portable measuring device.
