More work required to erase radiation in Fukushima
By Rebekah Moan
Wednesday, December 4 | 10:50 a.m.-11:00 a.m. | SSK11-03 | Room S405ABThe amount of radiation in Fukushima City, Japan, after the Fukushima Daiichi nuclear power plant accident in 2011 has decreased due to the removal of contaminated surface soil and tree leaves. However, some radiation still remains, and more effort to remove contaminated materials is necessary, researchers will report in this Wednesday session.

Ditch chest x-ray for tuberculosis, researchers say
By Rebekah Moan
Tuesday, December 3 | 3:30 p.m.-3:40 p.m. | SSJ06-04 | Room S404CDScreening chest radiography among people with positive tests for asymptomatic purified protein derivative is a low-yield study for detecting active tuberculosis (TB), so it may be time to reconsider this universal recommendation, according to New York researchers.

DR, CR benefit from antiscatter grid
By Rebekah Moan
Tuesday, December 3 | 3:10 p.m.-3:20 p.m. | SSJ06-02 | Room S404CDIn this presentation, researchers will describe how using an antiscatter grid in adult bedside chest exams significantly improved perceived image quality for both mobile digital radiography (DR) and computed radiography (CR).
