    i checked my answers with My Physics Teacher.. he told i was correct.

    i wrote these...

    1. Take repeat of readings and average.
    2. Avoid parallax error when measuring the length of pipe.
    3. Avoid zero error when taking measurement

    i m pretty much sure now . because i have confirmed with other site as well.

    Actually in my textbook it says beta particles can travel 5000 cm through air....so I wouldn't be too confident.

    To improve the test can you say: use a more accurate/ precise ruler (mm), use same type of pipe?
