        }
        if(!this.worldObj.isRemote){
            this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, explosionRadius, true);

Look at MovingObjectPosition.typeOfHit. Also, I don't believe you should be calling setDead on the client for an entity which exists on both the client and the server.
