Hi Roy and welcome to GoY, could you take photos of both the radishes and tomatoes and add them to your question, will make it easier for us to answer.

Maybe, maybe not - viruses usually cause distortion as well as mottling. Photographs would be helpful - could be a nutrient deficiency or a fungal infection.
