I am Japanese. Sorry, I don't understand what you want to know. Talking about the Kanji radicals, they are always put on the same places. へん is always on the left side つくり right かんむり top あし bottom かまえ around たれ top to left にょう left to bottom like that. We memorize Kanjis by writing again and again. While we doing that, we scarcely think about radicals. We learn about 1,000 Kanjis in elementary school, and (I think) 500 ～ 1,000 more in junior high school. Radicals are parts of Kanjis and because they have meanings, they help us to memorize Kanjis.
