Nuclear Body is a project carried out by Janez Janša with the consultance of the Oncological Institute of Ljubljana's Clinic Centre and supported by the Ministry of Culture of the Republic of Slovenia and the City of Ljubljana's Cultural Department.

It's the result of a research about one of the diagnostic techniques used in the field of nuclear medicine: radio-isotopic scanning or schintigraphy.

This technique allows the evaluation of a body organ's state by rendering on a computer monitor a digital image of it.

An isotope, introduced intravenously into the patient, after reaching the target organ starts to emit gamma ray, which are than detected by a special gamma camera.

By following methodically this procedure the whole artist's body was "copied" and "paste" into a virtual dimension.

Rather than a diagnostic technique, in Nuclear Body, schintigraphy is seen as a possibility to create an objective virtual double of a body, which could be used further on as its representation in digital environments.

Nuclear Body is presented as a computer based video installation.
It was premiered in March 1999 at the Ljubljana's Cultural and Congress Centre Cankarjev dom in the frame of the festival "the Beauty of Extreme II".
