Cook pasta according to package directions.
While the noodles are cooking, put the peanut butter, water, soy sauce, lime juice, chili paste, brown sugar or honey, and garlic in a food processor or blender and process until smooth.
When the pasta is cooked, drain it and return the pasta to the pot. Add the sauce and toss until well coated. If you need to add more hot water to loosen the sauce so it distributes easily over the noodles, add more.
Turn the pasta into a shallow serving bowl and top with the radishes and scallions. Toss and serve warm.
