Without protection, astronauts can acquire acute and chronic health problems from prolonged radiation exposure. Females have a much higher risk of cancer from radiation, studies have found. That’s why they have lower career exposure limits for NASA.
In this age where people can’t practically live without their phones and wireless devices, concerns about the potential health effects of EMF persist.
Most medical radiation incidents happen because of human error.
In some cases, it’s purely accidental. Other times, it’s when standard procedures are not completely followed because there are other ways perceived to be more efficient and fast.
On September 30, 1999, three Japanese workers at a small nuclear fuel preparation plant received high doses of radiation, with two of them dying from full-body radiation doses.
To minimise the risk of radiation exposure and its associated stochastic effects, radiologists and other healthcare professionals follow strict radiation protection guidelines and employ safety measures.
The bursts of energy from various solar events constantly hits the Earth’s atmosphere and can actually affect communication systems and the biological DNA. This is why cosmic radiation is a concern for astronauts and space equipment.
Wonder why many exit signs light up even when the power is out? That’s because these contain tritium, a naturally-occurring radioactive isotope of hydrogen.
Continuous monitoring and automated reports offer significant cost savings and greater operational freedom for staff, improving overall productivity at work.
Using the same equipment and exposure settings for adults may result in excessive radiation exposure when applied on smaller patients like children.
Handling and transporting radioactive sources carefully is critical. People involved should receive proper training from classifying, packing, marking and labelling, to segregating radioactive materials.
