A new version of the dose calculation program, JEUNESSE-2 code, was developed which copes with external neutrons as well as photons. The code is capable of calculating the effective dose E for six different age groups: 0-, 1-, 5-, 10- and 15-year, and adult. The continuous function of the radiation weighting factor and the new tissue weighting factors, specified in ICRP Publication 60, were employed in the calculation of E. The Monte Carlo code MORSE-CG was incorporated in the JEUNESSE-2 code to calculate the transport of neutrons and produced γ-rays from a source to organs or tissues of the phantoms. A sample calculation for isotropic neutron incidence showed a significant age dependence of E. A comparison of the resultant E for adult males with other results gave good agreement.
