    "abstract": "For interactions involving two or more nucleons it is useful to divide pions\ninto three classes: potential, radiation, and soft. The momentum threshold for\nthe production of radiation pions is $Q_r = \\sqrt{M_N m_\\pi}$. We show that\nradiation pions can be included systematically with a power counting in $Q_r$.\nThe leading order radiation pion graphs which contribute to NN scattering are\nevaluated in the PDS and OS renormalization schemes and are found to give a\nsmall contribution. The power counting for soft pion contributions is also\ndiscussed.",
