Q1
Which of the following are NOT tests which are used to assess the performance of astabilization or solidification process?
a. corrosion test b. EP TOX c. paint filter test d. TCLP
Q2
Given that you receive a dose of radiation of 1 milli-rad, the highest tissue damage wouldresult if the radiation adsorbed was in the form of:
a. Alpha b. Beta c. Gamma d. X-rays e. all the same
Q3
When a radioactive isotope decays by emission of an alpha particle:
a. an element with a lower atomic number results b. the same element with a different molecular weight results c. an element with a higher atomic number results resultsd. there is no change in the element or its molecular weight6.
Q4
When a radioactive isotope decays by emission of a beta particle:
a. an element with a lower atomic number results b. the same element with a different molecular weight results c. an element with a higher atomic number results results
d. there is no change in the element or its molecular weight
1) a,c
2} c
Gamma particles are often considered most dangerous type of radiation ,alpha and beta are charged particles where as gamma particles are form of energy,they have penetration power and defuse through cells.\
3) a
In an alpha decay nucleus release an alpha particle and results into an element which has lower atomic number by 2 and mass by 4,different element is generated.
4) c
In an beta decay one of neutron in necleus suddenly changes into proton causing increase in atomic number of an element
