Take numbers form two intervals in concentric circles in Julia

I am trying to take numbers from two intervals in Julia. The problem is the following, I am trying to create concentric circles and I need to generate vectors of dimension equal to 15 filled with numbers taken from each circle. The code is:

       rmax = 5
       ra = fill(0.0,1,rmax)
      
       for i=1:rmax-1
            ra[:,i].=rad/i
            ra[:,rmax].= 0
        end
        for i=1:3
            ptset = Any[]
            for j=1:200
              yt= 0
              yt= rand(Truncated(Normal(0, 1), -ra[i], ra[i] ))
              if `-ra[(i+1)] < yt <= -ra[i] || ra[(i+1)] <= yt < ra[i]`
                push!(ptset,yt)
              if length(ptset) == 15
                  break
              end
              end
      
            end
         end

Here I try to take elements that fulfill one of the two conditions -ra[(i+1)] < yt <= -ra[i] or ra[(i+1)] <= yt < ra[i], i.e. I would like to generate a vector with positive and negative numbers. I used the operator || but it seems to take only the positive part. I am new in Julia and I am not sure how to take the elements from both parts of the interval. Does anyone has a hit on how to do it?. Thanks in advance
