Abstract
The cosmic neutron intensity at sea level was monitored in the South C hina Sea where the vertical cut-off of geomagnetic rigidity is highest . The lowest neutron intensity, measured near the geomagnetic latitude at zero degrees, is 1.13 +/- 0.12 n Sv h(-1). Land survey on the near by coral reef yields a lower reading. Shipboard data in the open sea a re also compared to those measured in harbors and further inland. The progressive decrease of cosmic neutron dose rates from ship to ground indicates that the air-sea-land interfaces play an essential role in a ttenuating the cosmic neutron intensity.
