Finding the @ character within a text, cell range

Hello,

I can't seem to find anything that's specific to what I'm looking for.

I'm trying to find a formula that will tell me the following:

1. Whether the character '@' exists within cell range A1 or A2 or both.
2. IF YES, return result 1, 2 or Both.

COLUMN A | COLUMN B
***@*** | xxxxxx

Appreciate the assistance.
