✦ Synopsis

Evidence is given that neutrons produced by cosmic radiation produce an important fraction of the residual background of counters used for x4C age measurements. Neutron monitoring is essential in order to check irregular variations of the neutron flux, as for instance produced by solar flares. During the solar flare of Feb. 23 the average background for the whole night was 2.5 times normal.
