Main purpose of subject is to manufacture geo-radiation meter to look for underground water at Suoi Rao commune (Chau Duc district) and Con Son (Con Dao district), besides, abnormal objects will be seeked in Con Dao district. 7 following subjects have been implemented after 18 months:

 Firstly, study eradiation theory with two new discovery: Field of secondary automatic geo-radiation level 1 (It is electromagnetic field of geochemistry and origins from chemical reaction occurred in rock formation and phases in geologic environment); and movement in elastic half-space generates particular closed current or local one and then, it forms electromagnetic field surrounding called Field of automatic geo-radiation level 2;

Secondly, study principles of design accounting of geo-radiation meter with “principle electromagnetic interaction field” and geo-radiation field.

Thirdly, experimentally produce geo-radiation machine with two machines: Geo-radiation machine BTX 08- version 02 and geo-radiation model BTX 09- version 03.

Fourthly, study underground water flow model experiment in the room and do reality experiment outdoor with conclusion that Secondary automatic electromagnetic field level 2 is characteristics of underground flow and the unique signal, parameter to realize underground objects in general and underground flow in particular of geo-radiation method.

Fifthly, apply geo-radiation method in searching to find underground water in Suoi Rao commune and Con Son. Result is that underground water position was found out in Suoi Rao commune with quantity and parameter of underground water artery as nearly exact as confirmation after drilling. In Con Dao, 4 regions were defined to have water underground with water amount and depth within 75- 100 m.

Sixthly, apply geo-radiation machine to find out abnormal source – revolutionary martyr in Con Dao (community grave of 75 soldiers in Con Dao). Measurement result defined total of 52 positions of remains divided into two regions in gardens of Mrs. Duong Thi My Hau, etc.

Seventhly, build method and usage instruction of geo-radiation machine.

Council highly evaluates scientific meaning and obtained results of the subject and this result gives economic efficiency (finding water source) as well as social issue (finding remains) for people of Ba Ria – Vung Tau province. At the same time, Council requires chairman to present more specifically usage panel of geo-radiation machine with more specific map of underground water. The chairman should gives recommendation with Provincial People‘s Committee, Department of Science & Technology to implement next stages of the subject. And the subject is ranked good level by Council.
