A cycling group says it would 'strongly oppose' mandatory laws for helmets for every day cycling.
It comes after cycling was revealed to be the most common activity leading to referral to Beaumont Hospital's national centre for treating traumatic brain injury.
A new study has found that of 26 patients with cycling-related head injuries transferred to the unit, only two were recorded as wearing a helmet at the time of injury.
Other commonly referred activities included Gaelic football, horse-riding and rugby.
The study was published in the Journal of Clinical Neuroscience.
However it does not differentiate between different types of cycling - such as sports cycling or leisure cycling.
Martina Callanan is deputy chair of the Galway Cycling Campaign.
She told Newstalk Breakfast cameras would be more effective than helmets.
"We strongly oppose mandatory laws for helmets for every day cycling.
"For a person cycling, a camera is better for personal safety cause this can record road traffic offences and provide digital evidence to [the Gardaí]".
"The solution to keeping people safe and feeling safe is two things: separate infrastructure for cycling - and this is being provided through the Programme for Government".
"And also we need to change our speed limits - we need to reduce the speed on our roads to 30 kilometers per hour in urban areas."
She said this is important for people "who are mixing on the roads - where we have bikes, SUVs, HGVs, buses, articulated trucks sharing the space".
"The report today is quite grim, but it's important to remember that cycling is a safe, normal and enjoyable activity."
"The report doesn't distinguish between sports cycling, leisure cycling or every day cycling".
"Unfortunately too many people are injured on our roads."
People are not legally obliged to wear a helmet or hi-visibility clothing while cycling in Ireland.
But the Road Safety Authority (RSA) recommends cyclists wear both for safety.
