Answer:
Given
Per Kg of body mass, there is 3 gram of potassium
And abundance of three isotopes are as follows
Potassium-39, Potassium-40, and Potassium-41. Have abundances respectively as 93.26%, 0.012% and 6.728%.
1) A body weighing 80 Kg will have 240 grams of potassium. And the amount of Potassium-40 will be 0.012% of 240 gram
= 240*0.012/100 = 0.0288 gram.
2) Dose in (Gy) = (energy absorbed)/(mass of the body) = ( 1.1*106*1.6*10-19)/(80) = 22*10-10 J/kg
Dose (in siverts) = RBE*Dose(in Gy) = 1.2*22*10-10 = 26.4*10-10
Answer:
The debates over vaccinations are often cast as arguments over the integrity of science. But they can just as easily be understood as conversations about power, writes Eula Biss, a senior lecturer at Northwestern University, in her book, On Immunity: An Inoculation. As it stands, all 50 states require specific vaccines for school-aged children, although each grants exemptions for students unable to be vaccinated for medical reasons. The power struggle—pitting parents against parents—arises in the 19 states that allow families to opt out of vaccination requirements by claiming a "philosophical exemption," whether based on personal, moral, or religious beliefs.
