Project summary

The main tasks of project:

- Review the existing models and available data on contaminants transport in atmosphere.

- Elaboration of enough simple (physical-mathematical) model and numerical code to calculate propagation of aerosols in boundary atmosphere layer.

- Model testing and verification by comparison of calculation results with existing measurement data on territory contamination in East-Uralian Radioactive Trace (EURT).

- Carrying out detailed calculations of territory contamination and radiation loading, caused by incident, took place at "Mayak" in 1957. Main results of proposed work are to be.

- Enough simple, verified and effective models and codes to calculate propagation of polydispersive aerosols in boundary atmos-phere layer.

- Getting (if possible) a new information about parameters of the incident in 1957 and radiation loading had been realized.

In this project the main ISTC aims can be realized in con-siderable degree; the activities of group of specialists, dealing with nuclear charge design, have to be turned into peaceful field – long time work on environmental protection problems.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
