It depends on the scale.
Some organizations only use a scale up to 12,
If that number is supposed to be pieces per million it is very small.
But, the Asthma Foundation uses a scale where 39 is low. A moderate number would be near 80. (This scale makes the most sense with your number)

Does pollen cause hayfever?
Yes, if you are allergic to it. There all sorts of pollen and the main ones that cause hayfever are grass tree and weed pollens. Mould spores also trigger allergies. It all depends on your sensitivity level or trigger point. If you have a low trigger point to a particular allergen - whether it is pollen or dust or pet dander - then it won't take much of that allergen getting in to your body through your nose to trigger your reaction. If you have a high trigger point then you might only get a reaction on the worst of the pollen days - or maybe you won't react at all because you never reach your trigger level. So reducing the amount of allergen in your immediate vicinity will help with hayfever. That's why people use pollen blockers and pollen barriers on their nose, and it's also why air purifiers in the home can be helpful.
