From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

Plutonium and the radioactive decay products of radon gas emit a particular type of radiation known as alpha particles. A team of researchers from the Medical Research Council's Radiobiology Unit have shown that alpha radiation may cause damage that is not immediately apparent.
The researchers discovered that bone marrow cells which had undergone alpha irradiation did not show any apparent signs of damage. But after the cells had divided several times in the normal way, the 'daughter' cells showed aberrations and damage to the chromosomes. The report concluded that such 'chromosomal instability could produce genetic changes that may contribute to the subsequent development of leukaemia.'
