✦ Synopsis

The two known radioactive isotopes of Beryllium (BeT and Be lo) are produced in the atmosphere in nuclear disintegrations initiated by cosmic radiation. The long lived B~ 10 (hal/lite 2.7 million years) is di/~cult to detect and has not yet been isolated. The short lived isotope Be T (halt life 53 days) is easily detected in rain water and should, therefore, be of interest in meteorological studies. The average concentration of Be T in 8 monsoon rains in Bombay amounted to 2400 atoms per cm s and is consistent with the production rates predicted by PetersX).
