HOW MUCH RADIATION IS DANGEROUS? Acute whole-body doses of radiation in the range of hundreds to thousands of millisieverts increase the long-term risk of cancer. Increases in leukemia have been observed beginning as soon as 2 years after exposure to doses above approximately 200 mSv, although some cases did not appear for 55 years.25 For tumors in solid organs, the latency period is in the range of 10 to 40 or more years. Reports from the ongoing epidemiological studies of the atomic ...

4 basic laws of thermodynamics correct answers zeroth law: states that 2 objects in thermodynamic equilibrium with a 3rd object are also in equilibrium with each other 1st law: states that neither mass nor energy can be destroyed; only converted from 1 form to another(conservation of energy) 2nd law: states that the entropy of an isolated system can only increase; heat is not transferred from low temp system to a higher temp system one unless additional work is done 3rd law: states that...

How did the field of marriage and family therapy evolve? correct answers - Changing social dynamics after WWII - family roles became less predictable and options for individuals increased creating more interpersonal tension - divorce rates increased - the world entered the atomic age and anxiety reached levels that made it difficult for the family to cope as a system - became more accepting of professional help - some clinicians believed that individual psychological problems could be bette...

IB Chemistry Unit 2 SL Latest Version Rated A+ Emission spectrum An emission spectrum is produced when an atom moves from a higher to a lower level. The line emission spectrum of hydrogen provides evidence for __________________ which converge at _____________ The line emission spectrum of hydrogen provides evidence for the existence of electrons in discrete energy levels which converge at higher energies. Continuous spectrum All the colours / wavelengths present merge smoothly in...
