Calculate your average annual radiation dose by filling in Tabel 15.7. Compare your annual dose to the U. S. annual average of 360 mrem (3.6 mSv). One mrem per year has about the same effect as increasing your calorie intake by 4%, or taking a five-day vacation in the Sierra Nevada mountains.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

a electronegativity decreases beacuse the size of nucleus is bigger.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
