Answer true or false. (a) Ionizing radiation refers to any radiation that interacts with neutral atoms or molecules to create positive ions. (b) Ionizing radiation creates positive ions by striking a nucleus and knocking one or more electrons from the nucleus. (c) Ionizing radiation creates positive ions by knocking one or more extranuclear electrons from a neutral atom or molecule. (d) The curie (Ci) and becquerel (Bq) are both units by which we report radiation intensity. (e) The units of a curie (Ci) are disintegrations per second (dps). (f) A microcurie $(\mu \mathrm{Ci})$ is a smaller unit than a curie (Ci). (g) The intensity of radiation is inversely related to the square of the distance from the radiation source; for example, the intensity at three meters from the source is $1 / 9$ of what it is at the source. (h) Alpha particles are the most massive and highly charged type of nuclear radiation and, therefore, are the most penetrating type of nuclear radiation. (i) Beta particles have both a smaller mass and a smaller charge than alpha particles and, therefore, are more penetrating than alpha particles. (j) Gamma rays, with neither mass nor charge, are the least penetrating type of nuclear radiation. (k) After one half-life, the mass of a radioactive sample remaining is approximately $50 \%$ of the original mass.
