Hi i'm pregnant 15 weeks and just started working in a dental office I'm a bit nervous about the X-rays they perform there and I safe?

Should I worry?.I work in the front office but where they perform X-rays is not too far from me is there something I can do or wear I just started about weeks ago here so they are not aware I'm pregnant.please advice!

🙏 Thanks

Update I can't tell my employer they will fire me I just got hired and I'm maybe like 8 feet away....or maybe a little more it's not a room with door it's more like a wall that divides 2 xray stations that are a little cornered but there is a lot of people that walk through the hall way wen the xray is taking place!
