Neutron activation analysis is an analytical technique in which a sample of material is bombarded with neutrons
Question:
Neutron activation analysis is an analytical technique in which a sample of material is bombarded with neutrons from a fission reactor. When a 35.0-g aluminum can is irradiated, it has an initial activity of 40.0 curies (Ci). The safety office won’t let you touch anything having an activity in excess of 0.100 Ci. Assuming all the radioactivity is from 28Al, which has an halflife of 2.28 min, how many minutes do you have to wait after bombardment before you can handle the can safely?
a. 17.0 min
b. 1.32 × 103 min
c. 19.7 min
d. 478 min
e. 476 min

In brief , I am a Research Scientist with Tutoring experience in Chemistry . I provide solutions from basic to complex problem in the field of chemistry, making student easily understandable on the issue and solve their doubts.
I obtained my 5 year Dual Integrated BS-MS Degree in Chemical Sciences from Indian Institute of Science Education &Research-Kolkata (INDIA) (IISER-KOLKATA). Currently I am working part time as subject matter expert in chemistry at Course Hero Inc. , Redwood city, California, US and at Preply . Its been almost 2 years of ongoing online tutoring in chemistry . Additionally, I have about 2-3 years of research experience in chemical and pharmaceutical field while working as graduate researcher in INDIA & as Marie Sklodowska-Curie Early Stage Researcher at University of Strathclyde, UK.
I would love to teach students at preliminary, intermediate and graduate level in the horizon of chemistry . Here I give a brief insight into my academic and professional life. I am graduated with Bachelor and Masters in Chemical Sciences (chemistry) from IISER KOLKATA, INDIA integrated with all field of science .During my study I helped student in academics to learn chemistry at graduate level . Tutoring is a integral part of my life. I believe in interactive form of teaching, Not just revealing answer but also providing logical step by step explanation which is needed to analyze the problem correctly. I believe in friendly teaching environment where students are encouraged to ask their doubts / questions from basic, generic level to advanced one .
