Radiation movement

Hmm. After reading this tweet (https://twitter.com/RustUpdates/status/626517278323003393) I started poking around, and I found this in BaseEntity. Does this mean if you find an item in a radtown, it has a chance of giving off radiation?

Code:

 public float radiationLevel
  {
    get
    {
      if (this.triggers == null)
        return 0.0f;
      float a = 0.0f;
      using (List<TriggerBase>.Enumerator enumerator = this.triggers.GetEnumerator())
      {
        while (enumerator.MoveNext())
        {
          TriggerRadiation triggerRadiation = enumerator.Current as TriggerRadiation;
          if (!((UnityEngine.Object) triggerRadiation == (UnityEngine.Object) null))
            a = Mathf.Max(a, triggerRadiation.GetRadiation(this.GetNetworkPosition()) * this.RadiationExposureFraction());
        }
      }
      return a;
    }
  }

 

Sure looks that way, but it could also be that current rad towns have a special entity (perhaps invisible) that is the radiation source.
