    Tbh, I'm glad he hasn't been around :pierre:
    Apart from his obsession with mentioning his A*s in Lang and Lit in one year, he wasn't too bad... Can't blame him, I mean, he's not exactly had the best life I don't think socially...

    Mayne he's socializing!

    Well the world doesn't seem to be ending, I don't think he is.

    X-rays can travel through tissues and not through bone, so the bone absorbs the x-rays but the fracture won't so will show up darker on the radiograph have I written enough marks?

    A bit vague, but I'd say it's because the plastic is transparent/translucent and can let light through whereas metal is opaque and doesn't let light through.

    Film badges used to monitor how much radiation a person has been exposed to?

    As film badges are exposed to more radiation, they get darken when they are developed.
    Metal can block some radiation such as beta so it will stop the film inside the case from receiving the radiation. When it is developed, it wont turn as dark as it should be (because it has only been exposed to gamma) which means that people may be exposed to more radiation than they think they have been.
