Ban the bomb: 70 years on, the nuclear threat looms as large as ever

Braving the jab for community immunity

Let’s be clear: immunisations matter. They matter a lot. We all have a complex and ever-changing ecology of microorganisms and parasites inside our bodies and in our community. A recent fatal case of diphtheria…
Hand held radiation monitors don’t detect inhaled plutonium particles which can lodge in the lung and cause long term damage. AAP

Just in case you missed it, here’s why radiation is a health hazard

The March 11 earthquake and tsunami in Japan and complicating nuclear crisis throw into sharp focus concerns about exposure to ionising radiation. What is it, how is it harmful, how much is too much? Inside…
