693/t1,, where is the neutron flux integrated over the pulse and t ,,,is the half-life of the produce radionuclide. 693 . t1,2 +INT/+,, is about 70 and hence the advantage of the pulsing activation is approximately 50/t,,, which means that activation with pulsing reactor is advantageous for radionuclides with half-lives shorter than 50 s. WestphalliOdeveloped considerably the loss-free counting of highly active samples although there is a small increase in the noise and he used it for very short-lived isotopes of 20 ms (24mNa,12B)to 800 ms (38C1, 'O7'"Pb).
