Radionuclides are monitored in the atmosphere for the signatures of nuclear explosions, as part of the verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Civil nuclear facilities, such as Nuclear Power Plants (NPPs) and Isotope Production Facilities (IPFs) are sources of anthropogenic radionuclides in the atmosphere and these signatures are sometimes indistinguishable to those of a nuclear explosion. In order to...

Two new cell lines, designated RE and CB, were derived from the eye of rohu, Labeo rohita , and the brain of catla, Catla catla , respectively. The cell lines were maintained in Leibovitz’s L‐15 supplemented with 20% foetal bovine serum. The RE cell line was sub‐cultured for more than 70 passages and the CB cell line for more than 35 passages. The RE cells are rounded and consist predominantly of epithelial cells. The CB cell...
