49. Conclusions:
Most countries in the region have small activity in basic Nuclear Physics research. Mostly radiation and medical applications. Very small number of scientists.
Exceptions: Argentina, Brazil, Mexico
Region has no large scale facilities in NP and no plans.
Small support from funding agencies even for maintenance of existing facilities.
